Easy $5 Water Guns

Step 6 Make a bunch!

Now make a bunch, and have some crazy water fights with your kids (and all the kids in the neighborhood). When everyone sees how much fun they are, they'll ask you to make them some. Feel free to charge them more than $5 apiece!

To fill the water gun, put the nozzle end under water and draw the piston back to suck water into the barrel. It's important not to draw it back too fast, or to try to shoot the water out too fast either. It takes a couple of tries to figure out the correct amount of pressure to use. 

One last thing... don't store the water guns with the pistons inside the barrels. You don't want the rubber washers to take on any memory.

Good luck!

This one of the best things I've seen on instuctables! Hopefully if I can find the parts I'll make some this summer

Thanks! I actually suggest taking a look at the waterzooka instructable, especially step #5. I've found that I like the simple building method in that instructable better than what I show here in mine. I made some water guns with O-rings similar to the waterzooka, and they have proven to last longer, and even work better than my version here. (If you can beat 'em, copy 'em!)

i guess i'll give you credit for this because you posted it first >:( but anyway I was having a water fight with some of my friends and I was running down a sidestreet, and unfortunately dropped my gun and broke it. After QQing for a couple minutes I thought to myself: "what would someone on instructables do?"
so then (still in instructables mode) grabbed the pump from the end of my broken premade watergun and found a small length of pvc in a neighbors recycling bin
(shh! don't tell anybody!!) but with the pipe and the pump handle i just needed an endcap... fortunately for me I constantly carry a credit card with duct tape rapped around it, using a pen ink cartridge as a mold I put about a half inch of duct tape around it with a piece of paper in the center (to make the duct tape not stick to the pen cartridge) i took the small duct tape roll with a hole in the center and put in the front of my pvc pipe with the help of some more duct tape and there you have it. an extremely ghetto water gun...

btw i only said duct tape 4 times and sorry for any grammatical errors

Awesome tutorial! Can't wait to make these with my husband. Any ideas on painting them? I thought Camo would be fun but wondering if the paint would just come off on the user's hands.

I'd use spray paint. It might wear off after time, but I think it would stick pretty well.

For painting pvc, regular spray paint wont stck unless you coat with a plastic priming paint, you need krylon fusion(then he can enter it in the krylon contest too), sometimes regular paint will work if you coat it with a protectant but his best bet is to go with a plastic paint

Hey, good tip. Thanks.

[clemsonguy1125]

No problem, I had some issues when I was painting one of my potato guns, no matter what paint you use, make sure you sand the entire pipe to

[solsed]

how do you fill them quickly? is it a slow draw up through the nozzle or do you separate and fill and then reinsert the plunger?

[seamster]

I guess I didn't explain that. You draw up water into the barrel by pulling the piston back. You just can't pull it out all the way.
