DIY Friday: Head-Mounted Water Cannon

So this may not be related to rocket science, but it is an awesome little project. Awesome. A head-mounted water cannon, courtesy of Make and John Young:

Let’s face it: At some point this summer, you’re going to be in a water fight. Whether it’s at a family barbecue or an office picnic, some 12-year-old is going to leer at you from behind 25 bucks worth of store-bought plastic, and that little punk is going to think that the orange and blue Mega Awesome Hydrolator 9000 they’re clutching is the last word, the ultima ration regnum, in neighborhood water warfare.

Think again, punk. With about two hours of effort and the parts listed on the next page, you can hack together a water weapon of such power, such style, such extraordinary and exuberant overkill, that you’ll be out of the store-bought leagues forever. Lock yourself in the garage, play the A-Team theme, and emerge at the end of your build montage with a pressurized, stainless steel, head-mounted water cannon that packs five gallons of icy-cold water at 100 psi.
