I need to build a water rocket for my science class. I have already made the rocket, but am struggling to make a launcher. Our teacher wants us to build it, not our parents, so it needs to be fairly simple. I already purchased a bicycle inertube valve, which is used by alot of people. I also need to make the launcher tilted at a 60 degree angle for best distance, NOT greatest height. Please be descriptive when answering.
I need to know how the bicycle pump connects to the mouth of the 2 litter bottle.

Put a bicycle valveinto the cap, but don't screw it in- it needs to come out. Have a "claw" that holds the neck of the bottle on the ramp.
When you remove the "claw" the water pushes out the valve, and continues to exit via the hole in the cap that the valve was in.

get a water bottle, decrease a small hollow on the cap, placed a million/2 of it as water, then upload baking soda. be beneficial you plug the small hollow, then while the reaction happens, pull the plug out and it will fly!
