Frequently Purchased Together
Everyone loves a film canister experiment… but in this digital-age, where can you find a film canister? We’ve been asking ourselves the same thing for a long time, but now, we are bringing back film canister science. These super-sturdy film canisters are the best we’ve ever seen and were made to ensure the biggest pop. Our activity kit includes 10 film canisters, 5 packages of Alka-Seltzer, 1 canister launcher and 1 pair of safety glasses. Lose a few canisters during your experimentation? No problem, we also sell them in bulk packages of 15 and 30. Launch the Flying Film Canister caps, or flip them over and launch the entire canister. The choice is yours. Recommended for children ages 6 and up.

What Does It Teach?
When you mix Alka-Seltzer with water you are in for an explosive lesson in air pressure and motion!
Science Fair Connection:
Launching a Flying Film Canister is tons of fun, don’t you think? So how could you use this simple and engaging activity for the science fair? The trick is to change a variable, create a new experiment, and then compare the results.
- Repeat the experiment using another of the pieces of Alka-Seltzer, but this time change the amount of water you put in the film canister.
- Once you’ve mastered the film canister rocket technique, it’s time to measure how far the film canister rocket flies across the room. After each trial, write down the amount of water you used in the film canister (the variable), the size of the piece of Alka-Seltzer (this should not change because it is your control), and the distance the canister traveled. What amount of water mixed with a quarter piece of Alka-Seltzer produces the best rocket fuel?
- After you’ve determined the best amount of water to use, try changing the temperature of the water. How does temperature affect the speed of the reaction? Does warmer or colder water change the distance the film canister travels?
- Use another piece of Alka-Seltzer to make up your own experiment. What do you want to find out? How are you going to do it? What are you going to measure? Go ahead and experiment! Just make sure you only change one variable at a time. Document your discoveries and get ready to share them at the science fair.
Remember, when you change a variable, everything else has to stay the same. For example, if you change the amount of water you’re using, you need to keep the Alka-Seltzer tablets as close to uniform as possible.
