Exploding Pumpkin- Halloween Science Chemistry Demos!

Sticking with the halloween theme, this is a cool experiment that a chemistry teacher did. He made incisions in the shape of the eye and mouth but not too deeply. Then the filled the inside of the pumpkin with flammable gas. Lastly he ignited the gas with a lighter and the result is what you see. A scary pumpkin coming to life right before your eyes.
