Who needs rocket fuel when you’ve got Alka-Seltzer?! 🚀 Our friend Jay Flores showed how a simple film canister and a tablet of Alka-Seltzer can create a mini rocket launch. Here’s the science behind it: When water and Alka-Seltzer mix, they create carbon dioxide gas. As the gas builds up inside the sealed canister, the pressure gets stronger and stronger… until the lid pops off and the canister blasts into the air!
