The UberSoaker

A couple years ago I found myself at a company picnic. Many Super Soakers were present and an impromptu water war of sorts broke out between the various branches of our organization. It was all in fun but my group was badly outgunned. As we walked back to our cars at the end of the day we were literally dripping wet and our shoes were "squishing" with every step. My boss looked over at me and said, "We will NOT be outgunned next year. Your performance evaluation depends upon it!"

In response, I built The UberSoaker.

How did it work? Very well. Too well, in fact. At the next company picnic there were a fair number of squirt guns around, but vanishingly few with the guts to use them. Everybody took one look at the UberSoaker and they knew they were gonna lose. After all, the UberSoaker has the performance of a garden hose!

Still, I've been approached on a few occassions since then concerning it's construction. It really was quite simple. So I've decided to make a quick little webpage to document the design.

Here's how it was done....

  1. Buy a small air tank for filling tires. These are often available at Wal-Mart or auto parts stores, but I got mine at McMaster-Carr.

  2. Take your tank over to your friendly neighborhood welding shop and have them install a 1" NPT female port on each end of the tank.

  3. On the top port, install a 1" ball valve. This will make it very easy to fill your gun with water; just open the valve and fill! When you've got enough water in there, close the valve.

  4. Make a trip to Home Depot, use your imagination, and buy whatever bushings, elbows, fittings, barbs, and clamps it takes to get from 1" NPT to a garden hose.

  5. Buy a cheap garden hose and a nice pistol-grip spray nozzle. Cut the last four feet off the hose and install as appropriate.

  6. Buy a low-pressure Palmer Stabilizer, appropriate mounting hardware, and a short length of braided high pressure hose (available at any paintball shop). Installation is pretty damned obvious, no?

  7. Buy a 12-20 oz. paintball CO2 tank. Duh.

  8. Mount the whole mess to a backpack of some sort as it's too heavy to carry any other way. In my case I used an ALICE pack with the 5-gallon water can attachment, a small piece of plywood, and some rope. Come on, this ain't rocket science!

Usage is simple. Just fill the tank with water, connect the CO2 tank to the regulator, set the pressure to about 60-70 psi (only needs to be done once), strap it to your back, and fire away! It really is that simple.
