About Film Canister Rockets Kit - Launch A Rocket With
The Eisco Science Fair line is aimed at students interested in STEM concepts included physics and engineering. Each kit engages learners to discover new ideas about the physical world through assembly and play.Vinegar and Alka-Seltzer react to create gas inside the closed canister. Pressure builds as the amount of gas increases. Eventually, the pressure pops the lid off the canister, allowing the canister to launch into the air! To understand why vinegar and Alka-Seltzer create gas we have to go a little deeper. Alka-Seltzer contains sodium bicarbonate, potassium bicarbonate and anhydrous citric acid. When water is added, the anhydrous citric acid and the bicarbonates dissolve and are able to react. It turns out that carbonates and acids always react to create water, carbon dioxide gas, and a salt. We can write it as a general chemical equation: Acid + Carbonate → Water + Carbon Dioxide Gas + Salt. This kit provides enough vinegar and Alka-Seltzer for at least 2 rocket launches. It is possible that with some experimentation by using additional water and breaking the tablet into smaller pieces, students can launch their rocket more than just twice.Kit includes two film canisters 2 packs of Alka-Seltzer tablets (4 tablets total), cardboard storage box, safety data sheet and instructions for assembly and experimental activities
