The Effervescent Launcher is a bubbly, high-flying science gadget that's so much fun to use over and over again.
Simply position the PVC launcher at the desired angle, place an effervescent tablet and water inside the tubing, and load a 35mm film canister onto the end. The CO2 gas generated inside the tube blasts the canister's top into the sky like a rocket!
Includes launcher, instructions and effervescent tablets. Requires 35mm film canisters (not included).
 Gift Wrap Available
