The Parts List
Here's what is used to make one water gun:
- 20″ of each: 1″ and 1 1/4″ PVC pipe (usually available in 10-foot sections, hence the suggestion to make six water guns at once)
- End cap for each diameter of pipe
- One 3/4″ plug (generally for use on 3/4″ pipe)
- Two o-rings with inside diameter 28mm, outside diameter 34mm, width 3mm. I found these in the hardware bins at an Ace hardware. If you can't find this size, you may be able to use whatever close size of o-ring you can find, using the adjusting method I will cover ahead.
Aside from the o-rings, I bought all my supplies at a Home Depot store.
There is one more secret ingredient – dental floss.
