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).
