How To Make a PVC Pipe Water Cannon

If you are the type who enjoys letting yourself go from time to time to have a lot of fun with your friends and family, then you have probably been in one or more water balloon or squirt gun fights in your yard or neighborhood. Whether it is to let all those problems slip away or to just have fun with your children and friends, there really is nothing like getting everyone soaking wet with a water gun and a skilled trigger finger. But if you don’t have the cash to shell out for an expensive water gun that will leave your friends in awe as you carefully take aim, you can still leave them in awe at the incredibly range of your home-made all purpose PVC pipe water cannon. Contrary to popular belief, you do not need a lot of money to beat people in a water war. In fact, there is a cost-effective way for you to be ahead of the competition, though you need to be careful—as the pressure of a PVC pipe water cannon can hurt quite a bit, so you need to be careful when building your own. Yes, with this article you will be able to build your own all-powerful water cannon—you just need to be willing to collect the materials and make a serious effort to building one. So if you are interested, then be ready to rule the watery battlefields and follow these simple steps:

  • Gather the materials you will need to build your cannon. This includes a two feet PVC pipe (about two and a half inches in diameter), a one and a half inch end cap (you should be able to buy it along with the pipe), another PVC pipe (about three inches long and an inch in diameter), a wooden dowel (two and a half feet in length and one inch thick), rubber-O rings, some pipe glue, a hand-held drill, some tape measure, and sandpaper. These can take a while to gather, but the water cannon makes up for it by being easy to make. Once you have gathered everything, continue on to the next step.
  • Determine how powerful your cannon should be. This step is as simple as drilling a hole at the end of the PVC piping (the one that is two feet long). To put it simply, the larger the whole, the more water is shot out and the less range it has. But the less range it has means the less powerful your cannon is, and that can be a good thing, because if you hit another person with a high pressure shot of water from your cannon, you could end up hurting him.
  • Build your water cannon. The next step involves your wooden dowel. You will need to insert that into your smaller PVC pipe, and glue the two together. Finally, roll your O-rings inside the smaller pipe, which has the dowel inside it to prevent leakage. And you are finished.

In order to properly use it, first, fill the large part of the water cannon with water. And then use the dowel and insert it in the cannon pipe first to let out a spray of water. The best part is you can make more of these to have a lot of fun with your family and friends.
