I love me some 40 schedule 1/2 PVC so when it got super hot today I decided to make one of those customizable PVC lawn sprinklers. Then I thought "hey, it would be fun to make a pvc water gun that connects to the hose". I happened to have a sprayer attachment that had a threaded end so I tried my pvc hose connector on it and batta boom batta bing we were in business. This "ible" is not super detailed cuz it was a rush job but as all you hero dads* know time is of the essence when you are trying to entertain and inspire your kids.

Materials (this is for the triple barrel version)
Approx 20 inches of schedule 40 1/2 PVC (usually it comes pre-cut length of either 2 or 4 feet)
1 cross slip connector
1 "t" slip connector
4 1/2 slip caps
1 garden hose 1/2" PVC connector (threaded one side and slip on the other. I got mine at Lowes next to the sprinkler heads)
sprayer with a threaded end
Hack saw for cutting the pvc
Drill with 1/8 bit

Step 1: Drill the End Caps

Drill holes in the caps that will go on the end of the barrel. I experimented with several configurations. This came in handy because eventually we went from single barrel to the triple barrel

Step 2: Set Up the Pieces

You'll have to cut these to the varying lengths (I did not show me cutting PVC cuz I am assuming everyone knows how to do that.) None of this was glued together. I purposely just hand fitted all these pieces because it was fun making up new configurations with the various pieces.

one note with drilling: I used a fine drill bit (1/8th) to make the holes. The smaller the bit the stronger the stream will be as well as the stronger the pressure.

Step 3: Slip All Pieces Together

Slip all the pieces together and screw it onto the sprayer gun. You'll have to be careful not to put the hose on full blast because most guns will come apart if you do (the pressure is too strong). If you really like a particular configuration you can always glue this baby together and then you'll really be able to crank up the water pressure.

Step 4: Alt Set Up: Rocket Launcher

As we experimented with different pvc configurations we realized that if you attach a cap (with no holes drilled in it) to the end of a pvc and then hold onto the straight piece while cranking the water on the cap blasts off like a rocket.
