To launch the rocket we first had to put the launcher together we used a bike pump, 1.5 L bottle, pressure gage , some water to put into the bottle and a measuring jug .
First we went down to the back field and then we set up the rocket away from any buildings and any trees then we first filled the bottle with 250 ml of water with a measuring cup and then we put the water bottle onto the launcher and pumped the pump up to 10 psi we all stood back while Lincoln pushed the trigger nothing happened for a few minutes then boom and it was off it didn't go very far so Lincoln suggested that we put some more water in it so we put 200 ml of water in it and pumped the pump up to 30 psi Lincoln pressed the trigger and it was off that one went quite high the we did 2 more launches the 3 one we put 250 ml of water in it and 45 psi then the 4 one which went the highest had 45 psi and 350 ml of water. We learnt a lot and we are now going to a rocket of our own.
