Introduction: Water Rocket Launcher in 30 Minutes or Less
Ever wanted to build a water rocket launcher but did not have PVC cement?
What if you lack of patience to wait for the PVC cement to cure overnight?
What if you want to build a launcher right now that you can use right now?

Step 1: Materials and Tools Needed
Length of half inch schedule 40 PVC pipe. I recommend at least three feet
Schrader valve
Gasket, electrical tape, o ring, garden hose washer etc.
hot glue
Tools
heat source (a lighter works well)
clamping device, pliers work well
hot glue gun
drill bit or any means to create a hole large enough for the Schrader valve.
bicycle pump

Step 2: Heat,Pinch and Seal One End
How to heat,pinch and seal one end of the PVC pipe.
Use you heat source to heat 1 inch of the pipe at the end.
heat until the pvc is malleable.
,
when the pvc is soft, clamp, twist and pinch 1 end of the pipe.
Optionally inject hot glue into the end of the pipe after heating it and before pinching and twisting. This guarantees a good seal. See photos for details

Step 3: Add the Schrader Valve
Drill the smallest hole that will allow you to tightly squeeze the Schrader valve into.
After drilling a hole attach the Schrader valve to the bicycle pump before inserting and sealing with hot glue.
pump a couple of times while the glue is hardening. This will prevent the valve being plugged with the glue.

Add a gasket to the launcher.
A single wrap of electrical tape will do.
