one of the easiest water rockets you will see how to make.
if you shoot this bottle rocket at yourself or at something else or break something with it i do not take responsibility.
this rocket goes under very high pressure and can go very fast and hurt somene else or hurt yourself so please dont be stupid with it and use it safely.
Step 1: What You Will Need:
Give a general description of the Step instructable is so easy you only need three things.
1. schrader valve
2. bottle cap
3. and a pump
a drill (or just a knife)
Step 2: Step One:
now get your bottle cap and make a hole big enough for your schrader valve to go through (make sure that you have to force it through so its air tight)
Step 3: Step Two: Shoot the Rocket
now all you have to do is screw the bottle cap onto a bottle (any bottle that your cap fits on). once it is on pump it to about 50 psi (do not over pump or it will EXPLODE) once at 50 psi aim the bottle up but not at your chin aim it away from your head and unscrew the bottle cap as fast as you can. then it will fly really high i dunt know how high but it goes pretty high.
p.s have fun an play safe
