This week we launched a rocket it didn't go far though it went really high into the air. At one point all you could see was a black dot. When it fell down we went to use it again though, the second time, the top part of the rocket blew off and a crack was in the middle of it. after that, we learnt that we'd need to either reinforce the top so you can use it multiple times.
What would you use to make your own bottle rocket?
