Air powered PVC water bottle launcher

How to make a water bottle launcher out of pieces of pvc. Can shoot Very long distances. What you need is: About 2 feet of 1/2 inch piping, two 1/2 inch threaded to 3/4 inch corners, two 1/2 inch threaded joiners, 2 feet of 3/4 piping, a 3/4 inch end cap, a popped bycicle tube, and a 1/2 inch threaded ball release valve thing. Tools you will need are, a drill, and pipe glue. Optional parts are, a soda can for a blast deflector. If all that just confused you, just look at the picture.

Step 1 The end Cap

This is important to make carefully because you do not want any leaks here. What you do is cut the plug piece out of the bike tube. Then drill a hole in the end cap that is just smaller than the tube piece. then use some kind of glue (I Used Loctite extreme repair)and put it on the tube piece. then hammer it into the hole you made on the end cap.

That tube piece is called a schrader valve.

I need a water bottle launcher that shoots them without having to stick the pipe into the opening (It's for an awesome airsoft grenade).Is it possible to do this by making this gun but increasing the barrel size to fit the entire bottle?

That would work but you may need a bigger air tank to have enough pressure to be able to shoot the bottle

This instructable has this thing where he makes a bulge in the pipe using a candle so the bottle will not fly off instantly. Heres the link if u wanna c it http://www.instructables.com/id/water-rocket-launcher/

I believe that is a schrader valve you find them on bicycle tires etc.

I have a bottle but it fits to loosely on the 1/2 PVC.Is that a problem with yours to?If so,how did you fix it?Great ible,by the way.

What kind of bottle is it? and there should be a tiny bit loose so what i do is wrap a piece of electrical tape around the pipe about one time so is has a tight fit and as the pressure builds it slides off the tape then shoots off.

Okay.

I also noticed that smart water bottles are a tiny bit tighter than the normal bottles i use. But the bottles i've been using are arrowhead 1 pint and .9 fl oz. , and those dasani bottles, and ive used smart water bottles, but smart water bottles work the best
