Sub Zero presentations are very safe. All of our experiments are very engaging for both students and staff members. The purpose of the presentation is to demonstrate scientific principles while using liquid nitrogen.  We take the 

The school presentation cost will vary by your local Sub Zero location. The price of the presentation is based on the number of students and staff, distance, and any additional add-on items requested. Please call your nearest location directly for special pricing.

Sub Zero will adapt the presentation material to the grade level of the students, but we cover the following educational scientific topics:

• Nitrogen Safety
• Atmosphere
• Elements: Nitrogen
• Condensation/Evaporation
• The Ideal Gas Law
• Water Crystal Structure

We need enough space for an 8’ table and room to walk around it. We can perform the presentation inside or outside based on the number of students. We do not need electricity.  Access to water is helpful, but we can bring our own containers if necessary.

Sub Zero will make ice cream for all students and staff at the conclusion of the presentation. We will be making the ice cream onsite and we can cater to most allergies that your staff or students may have. Please disclose the allergies before the presentation with the Sub Zero owner, so we can come prepared.
