Science of Curling – Why Does a Rock Curl?
We epxlore the peculiar physics that accounts for the curl in the stone as it slides across the ice.

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?

The Science of Powdery and Grainy Material
Bulk containers of grainy material like rice or sugar often behave in counter-intuitive ways. They flow like fluids, but they can lock solid under pressure.

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!

How Does a Rocket Work?
A rocket is a vehicle that generates thrust by powerfully ejecting fluid exhaust from its engine. Even a fire extinguisher can serve as a rocket engine!
-
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!
