Show Me Some Science! Energy in Food

Food contains chemical energy that our bodies need to function. One way to measure the amount of energy is to burn the food and see how much thermal energy is released.

What’s Happening?

Zach and Spice saturate foods with liquid oxygen and set them ablaze to see how big the fire gets! Just like in our Liquid Nitrogen Flaming Pretzel Episode, we use liquid nitrogen to condense oxygen out of the air. Since oxygen is required for things to burn, an excess of oxygen allows them to burn quickly, to remarkable effect!
