Mist jet motor test part 2

the first test wasnt so great so i took the top 2 2L bottles off and tryed it again we saw  better results the launch pressure was 115 psi to replicate a real launch and 1000ml water the intial thrust was alot stronger then i imagined so strong in fact it broke away from the guide rail snapped a clamp which was holding the nose in place which was secured to the guide rail and moved the whole launcher to one side so there was loads of thrust
