Today we make some film canister rockets! This one is really easy, super quick and mega fun
Things you need for your mini rocket:
Lets Do It!!!
Firstly, half fill your film canister with luke warm water
Now you need to do this part FAST!!! Drop half an Alka-Seltzer tablet into the film canister, then click on the lid and flip it upside-down……..
Then stand back and watch it go!
This is really quick and effective, but how does it work? ………
The Science Behind The Film Canister Rocket
When the Alka-Seltzer tablet hits the water a chemical reaction occurs and CO2 (carbon dioxide) is produced. When enclosed inside the film canister the gas produced starts to build up pressure inside the container until there is enough pressure to force the lid off. This sudden release of energy thrusts the container into the air!
For a larger thrust experiment check out our pop bottle rocket!
Try experimenting by changing these variables:
