The rocket launcher was already assembled so the class went down to the field to with the rocket go off but be went through some procedures to get the rocket launch read.
First, they made sure that the assembled rocket launcher was facing up so it wouldn't hit anything. Second, they got the measuring cup and filled it up with 250ml of water and poured it all into the soda bottle then finally we connected the bottle to the rocket launcher.
Lincon was the one who would press the button so that the rocket would launch and Mrs Williamson did a recording of all the launch attempts while some kids got to pump pressure into the soda bottle.
For the first launch we did 10psi and 250ml of water which didn't launch and had a ten second delay. For the second launch, we did 30psi and 200ml of water and the bottle successfully launched off the launch pad.
For the third launch, we did 45psi and 350ml and it was a successful launch which managed to go higher than the one before. For the last launch, they put 45psi and 350ml and outu of all the rockets that were launched, it was the highest.
The test launches were really fun and I can't wait to see how high the finished rockets will go.
