Science Presentation Manual

Mobile Events are a crucial part of owning a Sub Zero franchise and generating sales. The more you are out in the community, the more free advertisement you will receive which will lead to in-store sales. This manual will help you learn about and feel confident performing science presentations.

Sub Zero Education Program

Science is an integral part of Sub Zero. The education program is an amazing way to increase brand awareness and bring Sub Zero into local schools. All franchise owners should be well versed in the education program and how to conduct a simple presentation for events and schools. You should also train employees/managers to do the presentations, we recommend also training the same person who does your marketing/sales. Having multiple people trained will also help when there are multiple presentations happening at the same time. Below you will find all the material you need on how you can bring Sub Zero to a local school near you.

Below are a few links that will help you understand how nitrogen works and give you some extra knowledge to share during your presentations.

Requirements and Training

To provide efficient and consistent catering, you will need to do the following:

• Purchase the necessary equipment

• Receive appropriate health certificates for your location.

• Follow Sub Zero’s standards in appearance, store branding, and uniformity of product.

• Receive training on a presentation, either through your franchisee training or by your Area Developer. If you are not able to receive either of these, you will need to be trained by the store closest to you. Before your first presentation, review the example videos on Nitrobase.

• Determine pricing structure. Because price varies per region, do research on surrounding Sub Zero stores to create a price point that works for you. Consider transportation fees beyond a certain radius. A pricing section follows, which help you with these decisions.

• Double-check contact information for accuracy before printing brochures.

• Familiarize yourself with the Sub Zero Science Presentation Manual.

Advertising, Sales/Marketing and CRM

Advertising

• Science presentation graphics collateral can be found at Sub Zero Printstore

Sales/Marketing

Sub Zero is a one-of-a-kind experience that sells itself; your primary job is to educate people on what we do! Marketing Sub Zero can be done multiple ways.

Each store should have a designated member of the staff in charge of science presentations and all they entail: sales, organizing, and execution. This employee should have Sub Zero's best interests at heart, have a social and outgoing personality, and know how to make a sale. It is highly recommended that this individual leave the store and market to local schools 3-20 hours per week depending on revenue. This is a way to form relationships face-to-face, which is important for communicating the Sub Zero concept.

Types of places and people to target:

• Local clubs

• Community & civic centers, libraries, and other public organizations

• Public schools

Bring plenty of flyers and leave enough for each science teacher to receive one. Ask the secretary to put one into each of their mailboxes, or if you can, ask to speak with the principal and sell to him/her. You can also get onto school websites and see their staff page; this will show the science teachers and emails.

Here is a sample email:

Where Sweet & Science Mix

“Want to spark a love of science in your students? Sub Zero Nitrogen Ice Cream can bring the power of the periodic table to your school, inspiring the rising generation with the wonders of liquid nitrogen. Our liquid nitrogen science education program can modify each presentation to fit our audience, whether it's elementary or high school students, and we share our gastronomical results at the end of each "experiment". Sub Zero Nitrogen Ice Cream wants to do its part in helping young people in local communities, which is why it offers its education program at a low cost per student, since our goal is to share our love of science with as many children as possible.

Combining Science and Ice Cream, Sub Zero Ice Cream teaches students a real-world application of science by demonstrating how liquid nitrogen can be harnessed to freeze fresh ingredients into ice cream. Not only does the process keep the children entertained with billows of non-toxic nitrogen "smoke", but we discuss concepts such as the elemental properties of nitrogen, gas laws, the Leidenfrost Effect (in a grade appropriate manner) and the application of science to food as well as other industries. Plus, the students get to eat the fruits of their academic labors with ice cream samples! Who knew learning could be so sweet?

Below is a list of what we will be teaching! If you are interested or have more questions please reach out to ___(name)__ at ___(email)___ or call me at _ (phone number) _.

Thank you and I hope you are having a great day!

CRM

Using ZOHO CRM is a crucial way to keep up with all of your orders, clients and leads.

Here is a link to a video explaining the CRM: WILL BE FINISHING SOON

Here is a link to the ZOHO CRM login: WILL BE FINISHING SOON

• Enter all leads into the CRM while marketing.

• Convert a “lead” to a “client” when they make their first order.

• Enter the order into the CRM to keep track. Corporate or your Area Developer will be cross referencing mobile event sales on the POS to ensure you are inputting all orders.

• Call them within a few days following the event to get feedback and ask for referrals. Alternatively, send a thank-you card with a short survey and SASE enclosed.
  
  Example: Thank you for the opportunity to teach your students about science. We are always looking for ways to improve our science presentations and would appreciate it if you’d take a few moments to fill out the enclosed survey and return it in the envelope provided. We value both positive feedback and constructive criticism. Thanks again for including us in your day.

Best regards,
[signature]

• Schedule periodic times to send out emails reminding them of your awesome experience and talk to them about future events.

• It is very important to keep a good relationship with your clients. Great customer service means everything, so make sure to go above and beyond each time.

• Last but not least, have fun! Science presentations are an awesome way to get out into your community and form long-lasting relationships.

Catering Policy

Science Presentations legally fall under the same type of service as catering.  Wiith that said, here is the catering policy that will apply to all mobile events including science presentations.  

Franchisees may cater events and conduct catering services within the radius of the “Protected Territory” as defined in the relevant franchise agreement, as long as the franchisee is in good standing under the franchise agreement and the franchisee is properly trained, qualified, and able to adequately service the customer and fulfill all material catering service requirements for the event. Note that franchisees have no ownership of or entitlement or exclusive rights to any catering leads or customer relationships. Franchisees have no expectation of any reserved territory or protected area with regards to catering or other off-site operations.

For any catering customers or events that fall outside of the Protected Territory, franchisees must receive approval from Sub Zero (or a designated Area Developer) to accept and service any catering customers and events. Please fill out and submit to Sub Zero (or the designated Area Developer) the following form to obtain such approval: http://bit.ly/2v2PGjm

If a franchisee has previously performed catering services for a particular customer, it is currently Sub Zero’s standard practice to approve the catering services for such customer as long as it does not materially and adversely affect a specific contract with or the existing customer relationships of any other Sub Zero TM franchisee and as long as the franchisee:

1) is in good standing under the relevant franchise agreement; and 2) can adequately service and fulfill all material catering requirements for the customer and the specific catering event.

However, final approval for any catering customer or event is subject to Sub Zero’s review and consent which may be granted or withheld in its sole and absolute discretion.

Pre-Existing Relationships In the spirit of teamwork and cooperation, Sub Zero hopes that franchisees will acknowledge and respect pre-existing customer relationships of other franchisees and forward any requests from such relationship to the appropriate franchisee.

Leads and Requests Obtained Directly by Sub Zero When leads for catering customers or requests for catering events are obtained directly by Sub Zero, such as through the subzeroicecream.com website, social media outlets, and other marketing channels, Sub Zero will attempt to forward the lead or request to the franchisee who: (1) is nearest geographically to the customer or event; (2) has a prior customer relationship with the specific customer or event; OR (3) otherwise has the resources and capability to service the customer or event. In certain cases, if a franchisee is unable or does not desire to service a catering customer or event (such as where the franchisee lacks sufficient catering training, resources, or ability or has a schedule conflict), Sub Zero will attempt to forward the lead or request to a franchisee who Sub Zero believes is reasonably qualified and able to service the customer or event.

Working Together In some cases, one franchisee may request that another franchisee service in its place a particular customer or event on one or more occasions (because of location, a scheduling conflict, lack of personnel or resources, and so forth). Also, two or more franchisees may determine that it makes sense to work together to service a particular catering customer or event. Again, in the spirit of teamwork and cooperation, Sub Zero presumes that franchisees will act reasonably and hold sensible expectations with regards to division of labor and resources and fee-sharing/referral fees.

Catering Pricing and Contracts To the extent permitted by relevant law, Sub Zero may establish minimum or maximum allowable prices on the catering products and services that franchisees offer and sell. Except as so specified by Sub Zero or as otherwise required by the franchise agreement or this manual, franchisees may determine the prices at which they sell products and services, as well as the terms and conditions of sale.

In order to develop and maintain the value of the Sub ZeroTM name and brand, Sub Zero expects that franchisees will act professionally and amicably when competing for catering business. To undercut pricing in order to win a specific catering customer or event out from under another franchisee that is known to have an existing relationship with that particular customer or event will be deemed a material breach of Sub Zero’s catering standards and guidelines.

Area Developer Involvement In cases where an Area Developer is present in the area, Sub Zero may forward catering leads and requests or otherwise defer to the Area Developer to determine how customers and events will best be accommodated within the area, in accordance with Sub Zero’s catering standards and guidelines.

https://desk.zoho.com/portal/subzerofranchisinginc/kb/store-operations-1/mobile-events/school-presentations/example-videos

Leidenfrost Effect

• Purpose: Demonstrate Leidenfrost Effect and Properties and Characteristics of Liquid Nitrogen

• Materials: Stainless Steel Bowl

• During this experiment, you will dispense a very small amount of liquid nitrogen into a stainless steel bowl. Explain that the liquid nitrogen is -321 Degrees, which can be dangerous if something is exposed to it for too long.  However, when a liquid comes in contact with something significantly hotter than the liquid’s boiling point, an insulating vapor layer is produced and keeps it from coming into direct contact with the object. This is called the Leidenfrost effect.  Point out the average temperature of the human body and the difference in this temperature from liquid nitrogen.

• ONLY THE PRESENTER OR TRAINED EMPLOYEE may dip their hand in the liquid nitrogen and quickly out again to show how the Leidenfrost effect is at work with their hot human body temperature coming in contact with the cold liquid nitrogen temperature.

• Compare this to putting water on a hot skillet.  If possible, without letting liquid nitrogen come into contact with any students, demonstrate liquid nitrogen rolling across the table and explain that this is similar and the same concept as water “rolling” across a hot skillet.  

• After the presenter touches the liquid nitrogen, have a student touch the presenter’s hand to show that it is not wet but in fact dry, to demonstrate that liquid nitrogen is a “dry” liquid, and not water at all.  

Liquid Nitrogen vs. Water

• Purpose: Demonstrate differences and similarities between Water and Liquid Nitrogen

• Materials: Water and Water Bottle, Food Coloring, Liquid Nitrogen

• Ask what the similarities and differences are between water and Liquid Nitrogen.  Point out their composition and elemental differences (H2O and LN2). Since they are both clear liquids, and we are very familiar with water in our daily lives, one might expect they are similar, but they are not in many ways.  Ask, “Which one do you think is more dense?” Fill water bottle ⅓ of the way full with water. Add food coloring to the water (red is suggested because it is a more stark contrast). Now add just enough liquid nitrogen to cover the top of the water.  (SAFETY WARNING: DO NOT add more than ⅛” of LN2 to bottle. Adding too much LN2 could cause the bottle to expand or explode if there is not enough space for evaporating LN2 to escape as it is expanding. DO NOT cap bottle with lid.) Point out that you can easily see the Liquid Nitrogen floating on top of the water in the bottle, so it is less dense.  Show the fog coming out of the bottle as the Liquid Nitrogen is evaporating and cooling the water vapor in the bottle and in the air. With the red water, students will be able to see ice forming in the water where the Nitrogen is cooling and freezing it.

The Liquid Oxygen Extravaganza

• Purpose: Demonstrate Condensation and Properties of Oxygen

• Materials: Stainless Steel Bowl (2)

• During this experiment, you will dispense liquid nitrogen into a stainless steel bowl and place it into another stainless steel bowl. As you let the nitrogen sit in the bowl, the liquid oxygen will begin to condense on the outside of the bowl. Drops of liquid oxygen will drip from the bowl as you hold it up showing the process of condensation.

• Another way to demonstrate liquid oxygen and its properties is to let the droplets of liquid oxygen condensing from the bowl drop onto a candle flame.  The flame will not only not go out, but spark or get bigger. Ask, “Why is the flame not going out?” Point out the properties of Oxygen as a flammable element.  

The Ideal Gas Law

• Purpose: Explain and Demonstrate the Ideal Gas Law, Show Condensation and Evaporation

• Materials: Stainless Steel Bowl (2), Balloon

• After explaining the simplified equation of the Ideal Gas Law (PV=T) and how when Temperature increases or decreases that Pressure and Volume should increase or decrease. Take a blown up balloon and place it into a bowl of liquid nitrogen. Use a Styrofoam cup to add more liquid nitrogen to help it shrink, or just roll the balloon in or put slight pressure on balloon to get it to shrink.

• Remove the balloon and show how as the balloon leaves the cold liquid nitrogen, it increases back to its original form. Also, show how the gas inside the balloon became a liquid and that it will now turn into a gas right before our eyes.

• For more audience participation, you may have a student or students blow on the balloon to help it expand, again showing how adding heat (from the hot air from the body) adds pressure and volume.

• The Ideal Gas Law is also a great way to answer the question, “How is Liquid Nitrogen made?”  It is through using the principles of the Ideal Gas Law (Air is pressurized, which adds Pressure and therefore increases Temperature, then the Temperature is cooled with a refrigerant which drops the Pressure and the Volume, and this process is repeated until air becomes a liquid.)

The Expanding Balloon

• Purpose: Demonstrate Evaporation

• Materials: Stainless Steel Bowl (3), Empty Water Bottle, Balloon

• Take a balloon, an empty water bottle, and a container of room temperature water. Ask, “When nitrogen boils and transitions from a liquid to a gas, does it expand or contract?  When things evaporate, do they take up less space, or more space?” Add approximately 2 inches of liquid nitrogen to the empty water bottle. Place the balloon over the top of the water bottle with no lid. Show the size of the balloon. Now quickly place the water bottle into the container or bowl of room temperature water. The balloon will expand until it is released off the bottle or until it explodes.

The Sub Zero Geyser

• Purpose: Demonstrate Evaporation

• Materials: Stainless Steel Bowl with Water, Empty Water Bottle

• Similar to the experiment of the expanding balloon, you will perform a similar experiment, but without a balloon on top. This will rather be performed with just an empty water bottle and liquid nitrogen allowing the students to see the pressure and water vapor blow into the sky. Add approximately 2 inches of liquid nitrogen to the empty water bottle. Place water bottle in bowl of water to let the liquid nitrogen evaporate straight out of the top of the bottle.  The visual presentation is strong as the students can see the cooled water vapor coming out of the water bottle (similar to a geyser) and watch evaporation occurring right before their eyes.

The Cryogenic Rose

• Purpose: Demonstrate Liquid Nitrogen as a Preserver of Life and Cells

• Materials: Stainless Steel Bowl, Fresh Rose

• Nitrogen can be used for a lot of things in the world today. Like the frozen rose, nitrogen can preserve the life of other plants and vegetables. Nitrogen makes it possible to send things across the world. Subzero utilizes nitrogen in our business as well.

Freezing Racquetball

• Purpose: Demonstrate how objects react differently when frozen

• Materials: Stainless Steel Bowl, tongs, Racquetball (2)

• Discuss observations of the racquetball at room temperature; its elasticity, bounciness, etc.  Freeze one ball by putting it into a bowl of Liquid Nitrogen and remove it using tongs. Holding both balls, ask students to hypothesize on which ball will now bounce higher when dropped at the same height at the same time, or if there will be any difference.  

• Objects are affected differently when they freeze.  Different temperatures affect many different aspects and traits of objects.

The Ice Cream

• Purpose: Demonstrate Sub Zero’s Ice Cream Making Process (Freezing)

• Materials: Stainless Steel Bowl (3), Ice Cream Spade (2), Ice Cream Scoops (2), 1/9th Cambro, Cream, Sub Zero cups, spoons

• Ice Cream is best made in batches when doing school presentations. The key is to make ice cream quickly. Have teachers scoop while you make large batches of liquid nitrogen ice cream. You will want to talk about the process while making your first batch, but for each other make ice cream quickly.

Sub Zero Presentation Script

Your presentations should showcase your own style and personality, please take this script and make it your own. You need to be giving the correct information but you also should be having fun! There is a section on Nitrobase of “How To’s” that will be helpful and includes visuals for your presentations. https://desk.zoho.com/portal/subzerofranchisinginc/kb/store-operations-1/mobile-events/school-presentations/how-to-s

Sub Zero Ice Cream Introduction

Hi, my name is _________, the Cool Chemist, and I love science! How many of you love science? (Raise your hand). How many of you love ice cream? (Raise other hand). How many of you love science and ice cream? (Raise both hands).

At Sub Zero, we specialize in making the best ice cream on the planet using science. We will talk more about our ice cream later, but right now, I want to focus on science!

Set Ground Rules

As a Cool Chemist, I like to ask lots of questions. Questions are one of the best ways to learn. If I ask a question and you know the answer, what should you do? (Answer: Raise Hand!). On the other hand, if things get too noisy, and I raise my hand up, what do you think that means? (Answer: Be quiet). Very good. We have a great group here! Let’s practice. Everyone be very noisy. (Raise your hand after a couple seconds and see how long it takes for them to be quiet. Repeat activity 2 times).

Matter

Science is the study of how things work. And all “things” are made up of matter. Have you learned about matter? What is matter?

Matter – Physical substance that can neither be created or destroyed.

This year you have learned, or will learn, about physical changes, heat transfer, chemical reactions, and more about the world around us. The world is a beautiful place. Also, you will learn about the Scientific Method.

Slide “Scientific Method”

The steps taken by Cool Chemists in the Scientific Method are:

• Ask a Question

• Create a Hypothesis

• Conduct an Experiment

• Observe what Happens

• Form a Conclusion

With our experiments today, we will follow the steps of the Scientific Method. I need all of you to help me create a hypothesis before our experiments.

Atmosphere

Everyone, I want you all to take a deep breath (Class breaths in). Now, let it out! (Class breathes out). One more time, breathe in! (Class breathes in), and breathe out. (Class breathes out).

Question for everyone: What did you just breathe in?

Answers may include: Oxygen, Carbon Dioxide, Argon, and Nitrogen.

There are other small gases, but those are the main elements found in the earth’s atmosphere.

Slide: “Earth’s Atmosphere”

These elements can be found in different physical states also known as the States of Matter. What are the different states of matter?

Slide: “States of Matter”

Answers may include Solid, Liquid, and Gas

When talking about the atmosphere, we talked about gases, but these can also be condensed to a liquid and frozen to a solid.

We need Oxygen to live. Plants need carbon dioxide to live and all other elements have their purposes, but what about nitrogen. What is nitrogen?

Slide: Nitrogen #1

Nitrogen is an inert element that is colorless, odorless and makes up about 78% of the Earth’s Atmosphere. One of the most common uses of nitrogen is as a coolant which is in a liquid state. At a liquid state, nitrogen is very cold. -321 Degrees Fahrenheit! 321 degrees below zero!

Slide: Nitrogen #2

To help us learn this, before every experiment, we will countdown to Nitrogen: I will yell MINUS! And then you say 3, 2, 1 Nitrogen!!! (Practice with students)

Now that’s really cold!

Physical Changes: Condensation/Evaporation

How do we take the nitrogen in the atmosphere and make it into a liquid? A Gas turning into a liquid is a physical change that occurs with the decreasing of temperature called condensation.

Slide: “Evaporation & Condensation”

Repeat after me. Condensation. (Class yells out “Condensation!”) Again, Condensation (Class yells, “Condensation!”)

Dispense Nitrogen from the tank into a bowl.

I hold in my hand a bowl of liquid nitrogen

(Blow into the bowl to show the vapor)

Question: What is the physical change going from a gas to a liquid?

Answer: Condensation.

Here’s our first experiment. Minus! (Class continues by saying 3, 2, 1 Nitrogen!)

Experiment: Liquid Oxygen Extravaganza

Question: What is happening to oxygen? Yes, the oxygen in the room is being condensed into a liquid right before our eyes.

Does anyone know what physical change describes a liquid turning into a gas?

Answer: Evaporation.

Evaporation is the physical change moving from a liquid to a gas. Minus! (Class continues by saying 3, 2, 1 Nitrogen!) Let’s do the experiment again.

Experiment: the Sub Zero Geyser

Question: What term do we use to describe gas to a liquid? (Answer: Condensation).

Question: And what do we use to describe a liquid to a gas? (Answer: Evaporation).

Condensation and Evaporation

Ideal Gas Law

We can talk about science all day, but who wants to see some more experiments? (Class screams in joy!) Before we continue, I need to teach you about the Ideal Gas Law. Say it with me, “Ideal Gas Law!” We must obey and follow laws. Elements too are held to standards and laws. Let’s examine what the ideal gas law is.

Slide: Ideal Gas Law Equation.

For our purposes, we are going to use a simplified version of the ideal gas law.

Slide: Simple Ideal Gas Law Equation.

We have here the equation PV = T. P stands for Pressure, V; for volume, and T; for Temperature. Now, let’s talk about math for just a second. Scientists love math. With both sides being equal, if one side of the equation goes up, what happens to the other? (Kids yells, “Go up!”) And when one side goes down? (Kids yell, “Go down!”).

Okay! We have a bunch of smart & cool chemists in this room. If I decrease the Temperature, what happens to the Pressure and Volume? (Kid answers, “They will also decrease.”). Okay, we are ready for an experiment now.

Blow up a balloon.

The Pressure and Volume can be seen easily with a balloon, but now I need something very cold. Do you know anything that I can use that is cold? (Kids say, “Liquid Nitrogen!”)

So liquid nitrogen is cold which will decrease the temperature, so what is your hypothesis on the balloon’s volume and pressure? Will it increase? Or decrease? (Answer: Decrease.).

Minus! (Class continues by saying 3, 2, 1 Nitrogen!)

Experiment: The Ideal Balloon

Repeat Experiment and review condensation and evaporation.

Science can be fun. It’s always cool to see things change as we observed this balloon get smaller, but who wants to see it get bigger? (Children scream!) The Ideal Gas Law says that if we increase the temperature that Pressure and Volume will increase and therefore get bigger!

Let’s observe. Minus! (Class continues by saying 3, 2, 1 Nitrogen!)

Experiment: The Expanding Balloon

Repeat the Experiment—Pop Balloon (with permission)

Again, we see the ideal gas law hold true. Nitrogen cannot disprove the ideal gas law.

Water Crystal Structure – Freezing

Biology is the study of living organisms. Biologists study plants and animals and human life. I want to talk about plants and conduct another experiment. I have a rose. I have a question for all you future cool chemists.

Question: What would happen if you put this rose in the freezer?

Let the students give some responses

Answer: Yes, It would turn brown and yucky! This happens because the rose reacts with oxygen over time. What do you think will happen when we flash freeze the rose with liquid nitrogen? Let’s observe what happens when we freeze the rose using liquid nitrogen. Minus! (Kids yell: 3, 2, 1; Nitrogen!).

Experiment: The Cryogenic Rose

Because the rose is submerged in liquid nitrogen the oxygen cannot react with the rose.

Nitrogen can be used for a lot of things in the world today. Like the frozen rose, nitrogen can preserve the life of other plants and vegetables. Nitrogen makes it possible to send things across the world. Sub Zero utilizes nitrogen in our business as well.

One more quick question, what would happen if I smashed this rose? Do you want to see?

Now the moment you have all been waiting for…

Minus! (Kids yell, 3, 2, 1; Nitrogen!)

Let’s make ice cream! And just like the rose, we are going to make ice cream using liquid nitrogen. Liquid nitrogen makes the best ice cream on the planet because of the small ice crystals. As you eat this ice cream, pay attention to your taste buds for the creaminess and density of this nitrogen ice cream!

Experiment: Make Ice Cream

Review the information presented with the class.

Eat Ice cream. Enjoy.

Link POS and Registers

Link POS has a menu tab on the top right corner of the screen. When you click this tab, you can choose a catering menu instead of the main store menu. This will pull up the following two titles and buttons. You are in charge of putting prices into these sections just as you would for the store menu.

CATERING

• Set-up Fee

• 2 oz Serving

• 4 oz Serving

• 6 oz Serving

• Waffle Cone (Each)

• Extra Travel (Per Mile)

• Extra Employee (Per Hour)

• Extra Hour at Venue

SCHOOL PRESENTATIONS

• Set-up Fee

• 2 oz Serving

• Extra Travel (Per Mile)

• Extra Employee (Per Hour)

• Extra Hour at School

When vending or doing any type of catering outside the store, please set up your second iPad as “Register 2” under the physical store settings. This will help when the nightly manager pulls the in-store deposit. They will need to only pull a deposit from “Register 1.” This will prevent any confusion with cash or checks that were given outside the store and are not physically in the store register. Be sure to communicate with the nightly manager when you are doing any sales on the second iPad so they know to follow this procedure.

When pulling a report for catering on LinkPOS, go to “Sales Summary,” keep it on “All Registers” and “All Cashiers,” and then put in the dates you want to view. Click “Preview” and find “Catering” under “Category Summary;” this will accurately show all catering and science presentation sales lumped together.

Science Presentation Flavors and Pricing

Standard flavors to be used are Chocolate, Vanilla, and Cotton Candy. We suggest using low-fat cream, as low-fat is typically lower priced and we are usually offering school presentations at a lower cost for school budgets to afford.  Some locations bring toppings but they do make a mess especially with kids serving themselves, and they cost more.

The following prices will give you an idea of where to price your science presentations. It is recommended that you get a second opinion from Corporate or a nearby store when making the final decision.

-Base set-up charge for the normal 1 hour service $50-$195.

-Per serving charge for the 1 scoop/2 ounces size $1.50-$4 for the standard 3 flavors.

-Serving minimum per event 35-50 people or $52.50-$200.

-Travel charges for over 10-50 miles away is $0.50-$0.55 per mile.

-Employee charge is $25 per employee per hour including travel time.

-Extra time at venue charge $35 flat per hour or $25 per employee per hour.

-Deposits are not usually taken for schools since they are very reliable.

-Full invoice price needs to be paid between 3 weeks before event to 7 days after event. Most schools are good about paying the day of when you bring the invoice to the secretary.

Transport and Operation Safety

Safety should always be your number one priority. Below are some guidelines that will keep you and your employees safe outside the store.

• Never try to lift the nitrogen tank (a full 50-liter Dewar is 140 lbs.) on your own; doing so can result in injury.

• Always use the “buddy system” when moving the tank or any equipment over 50lbs (OSHA Standard). A dolly can also be used to help with transporting the tank.

• Understand all safety features on your nitrogen tank.

• Know how to safely fill your tank (wearing gloves/eye protection, have correct valves open for venting).

• Know how to transport your tank. This includes:

• Securing it well in the vehicle.

• Ensuring a window is cracked in a closed vehicle to allow ventilation.

• Using a dolly or lift gate to transport in and out of vehicle.

Uniforms

Suggested uniforms:

• White Lab Coat

• Black slacks

• Black non-slip shoes

• Hats, Visors, or other appropriate hair control that satisfies local health department requirements.

GOOD LUCK!
