  1. The Urine effect by Anonymous Coward · · Score: 3

    Yep. Pee in a supersoaker. Nothing makes people run quite so fast. Mind you, a little FOOD coloring in water IS the pee but no need to tell your friends that. Example: At party, PRELOAD supersoaker with FAKE pee water, hide in bathroom. Carry around second EMPTY soaker. Ask friend who is in on the gag to DARE you to fill it with your pee. Take the empty soaker to the bathroom, make the switch. Come out and spray someone. Aim for someone in white for the best effect. Adding SALT to the water will give it a funky smell. Sit back and laugh at how people will freak out at your poor taste and jugement. While you have the partys full attention, shoot it in your mouth, drink it and watch the reaction. Priceless. Note: Do not aim for people who are old or very young. Kids don't mind if you spray them with pee it seems and old people freak out too much. So aim for adults or pets. For more fun, spary the PEE into your buddys mouth.

    Cats dislike water on their skin. From what I hear, their saliva contains an enzyme that keeps them from stinking, alerting their prey as cats are predators. Water washes away this enzyme.

    Neighbor cat used to get on the fence and yowl at our cats something fierce. I kept a super soaker handy but he always ran away when he saw me coming. One day, his luck changed. He had made the mistake of getting too close to our cat on the fence, and when I came out, he didn't dare turn tail or he would have lost face with our cat, so he stood his ground while I got closer and closer. It was a very satisfying march to the fence once I realized this. His yowl got a bit higher in pitch as panic set in. I unloaded on him from about 5 feet away, a good hard super soaking. He never bothered our cats again. A truly satisfying day!

  7. Flammable Materials by tbo · · Score: 3

    Does anybody know what happens if you fill a supersoaker with gas, and light the gas as it sprays out? Instant flamethrower? Or do you just blow yourself up? I've wanted to try this to get rid of wasp hives, but was a little scared about the possibility of horrible flaming death ("tastes like burning").

    Another cool variation would be a 50/50 mix of water and alcohol. Spray on something valuable, ignite, watch people scream before they realize it's not actually being hurt by the flames (because alcohol doesn't burn very hot and the water protects it from the heat).

      I've got the double-barreled model (forget what the number is offhand)... Was wondering if you could put a fuel in one tank and a strong oxidizer in the other, so they go off when they hit the target and mix. Come to think about it, methanol and decently concentrated Hydrogen Peroxide'd probably work... Or maybe RFNA and whatever you happen to have on hand?

      But then again, the oxidizer would probably burn the tank it was in, along with the plastic plumbing... I hear that bleach and brake fluid work though...

      Best thing I've ever seen shot out of a water gun was unset jello (which sets rather nicely in the cool spring air). If you want to be a cruel bastard, I've seen bleech done too.

    We used to fill 2 Liter bottles with cold water and dry ice (don't use hot, as the bottle will expand, cold keeps the plastic from melting) and seal it up. After moments, the thing would blow.

    The good ones happened when it didn't blow, and some brave sould had to whack it with a shovel. Seeing a guy hit in the sac with a speeding bottle cap is funny.

    Certain bottles would fail differntly. The plastic juice bottles would blow the cap off. The top would just blow itself off the threaded part. It would still be screwed on, just "open" at the top....

    Soda bottles with burst from the side, I guess the tops were pretty solid.

    Aspirin bottles just became flying shrapnel. (Damn childproof top)

    Gulden's spicy mustard bottle made a friggin mess. The metal top would hold, but the sides wouldn't.

  9. Super-soakers aren't the best by legLess · · Score: 3
    IMHO, nothing beats a Stream Machine (link to out-of-stock page, with photo, on Amazon). It's really simple - a long plastic tube with a nozzle at one end and a plunger with pistol grip handle at the other end. Stick in bucket, pull plunger, point at target, push plunger.

    Now, it might not sound that great, but it's really very nice. Your GMP (gallons-per-minute, like a shower head) is potentially much higher than a Super Soaker. The release rate is totally up to you - a little or a lot. I can shoot one about 30' straight up, and I'm not exactly muscle-bound.

    I once got in a water fight with one of these things; my buddy had a hose. Sure, I had to carry around a bucket, but he surrendered pretty fast after I shut his hose off ;)

    This got me thinking, what if you took a CO2 tank from a paintball gun, removed the handle from the slide and made a pneumatic piston for the main chamber. If you used a solenoid and pressure sensor to avoid shattering the gun you could have an "auto-pumper". That would REALLY kick some ass at a squirt gun fight.

    The article went straight from squirt pistols to second generation Super Soakers, without ever mentioning the originals. The original Super Soakers weren't of the 2 reservior variety, but were a single reservior into which you pumped more and more air, not water, to build pressure.
