Exploding Water
Water is composed of hydrogen and oxygen. With the help of a little electricity, we can separate water into its component gases with explosive results!
-
Liquid Oxygen and Combustion
The rate at which a fire burned is governed by the availability of oxygen. Fires burn at a phenomenal rate when the concentration of oxygen approaches 100%!

Never Put Water on an Oil Fire!
A simple safety tip, very graphically illustrated. Water makes oil fires much, much worse!
-
Flashover Fires
Fires burning in enclosed spaces can very quickly erupt explosively. How long will it take for a smoldering bed to catastrophically flare into a fireball?

Hydrophobic Materials Keep Water Away!
Lots of materials absorb water, but what sort of materials actually repel water, and how does water behave around them. Here are some fun ways to stay dry when you’re surrounded by water!

Body Heat
Our body creates heat through the chemical reactions required to move muscles. With the help of some candy, we can illustrate just how much heat is available when we break apart sugar molecules!

Play With Polymers
A polymer is a long chain molecule composed of smaller, similar units bonded together, like the boxcars in a train. These demonstrations illustrate some of their remarkable properties!
