Dear friend,
I made things explode this week! I made a film canister rocket. It was really fun. Here I'll teach you how to do it:
You will need:
Empty film canister
Alka-seltzer
Hot water
paper for the outside (optional) ( I don't recommend this because the paper rips easily when wet)
Safety glasses
Put the hot water half way in the film canister and then put the Alka-seltzer tablet in the canister. Now, you have to be quick when you put on the lid or it won't pop up because there won't be any pressure in the canister. Once you have the lid on and it's on the ground run back as fast as you can so it won't hit you.
O.K this is how it works, the chemicals in the tablets react with the water, then the pressure builds up which makes the canister fly up in the air! O.K I have to go. Keep checking the mail!
Ali
