The "Pop a Rocket" project and the "Tube Kazoo" project are two Bill Nye-created physical science experiments suitable for a science fair. The rocket project uses film canisters, baking powder and water for two-part fuel system that safely explodes, while the kazoo project repurposes a cardboard tube, wax paper and a rubber band into a homemade instrumentContinue Reading
To perform the "Pop a Rocket" experiment, put a teaspoon of baking powder in a film canister with a plug-style top. Fill a second canister about half-full with water, put on safety glasses, and then pour the water on top of the powder. Working quickly, snap the top on, shake the canister once, and place it upside down on a flat surface. If performed correctly, carbon dioxide gas makes the canister fly up in the air like a rocket.
The "Tube Kazoo" experiment displays how sounds made in the hollow part of the human head, via humming, transfer to a homemade instrument for a kazoo-like sound. To make the instrument, punch some small holes in the side of a cardboard tube with a pencil. Place a piece of wax paper over the end of the tube, and secure it with a rubber band. Play the instrument by humming into the open end, covering the holes to vary the sounds.Learn more about K-12
