Introduction: Water-Weenie

About: Will Bosworth, developing projects for HowToons @ SquidLabs.

Looking for a good waterfight? Water hose too short? Soak those pesky neighbors or water the plants on the far side of the yard with this 3-part water-weenie!

Step 1: Parts & Tools

1 bicycle innertube (preferably used), 1 hose clamp (sized for water hose), 1 female-male hose connector with flow toggle switch (2.50 @ homedepot).

knife & screw driver.

Step 2: Prepare Innertube

Cut the innertube so that there are two open sides. If recycling a busted tube, cut out any holes. Keep the nozzle if possible.

Next, tie a simple knot at one end of the open innertube.

Step 3: Assemble the Weenie

put the open end of the innertube over the male side of the male/female hose connect. Tighten the hose clamp over this assembly.

Step 4: Filling the Weenie

screw a hose into the weenie. turn on hose. open the flow switch on the weenie. watch the weenie fill up. (note: the innertube will burst if filled to much. We've observed that the innertube explosion is not too violent, but be carfeul!)

Step 5: Free the Weenie

Turn off hose. close flow from hose to weenie. unscrew hose from weenie. (unscrewing the hose can be a little wet. if you close the flow to the weenie before turning off the hose it will be wetter)

Now, The flow switch on the weenie is the trigger for shooting water out.

Step 6: Play With the Weenie / Strut Your Stuff

    Gas burner nozzle, surgical clamp, surgical tube, tie off other end. We used to hide them under clothes and walk down the hallway with the clamp in our hand and just shoot when passing others. The burner nozzle did well to concentrate the spray. Just make sure that you don't wrap them around your body as they constrict a lot when deflated. As one yoyo kid discovered....

    i'd like to see someone cut an innertube so that there is one open side, ha! :D

    I used to make these with my friends some 20 years ago to pass the hot summers in SoCal. Our version used surgical tubing that we got from a scuba shop and a pen cap. Simply knot the tube on one end and stick the pen cap into the other. We'd usually wrap some rubber bands tightly around it to keep it in place. To fill 'em up we'd stick the pen cap into a water fountain and turn on the water. Then just keep your thumb over the end and let go to soak somebody.

    That is EXACTLY how you make them. Or was that just a southern cal thing! I want to make these for my kids. Water fountain...exactly.

    This is exactly how we used to do them. My parents wouldn't let us have "guns" back in the day, so we improvised: my mom worked at the hospital so surgical hose was an easy find. My dad owned an advertising business, so those click-pens were plentiful. Combine for fun.

    my uncle made something like this i should post an instrucable on it. I will when i get the time. whenever that will be.

    looks cool, like the stance, ready for action with the salami, nice.

    I used to make the surgical tubing water weenies too! We would fill them by simply sticking the pen tip into one of those hose nozzles that were tapered with a small hole (for a thin, forceful stream). One hot summer day while filling mine, the tubing burst in my face and I caught a piece of rubber in the eye. No major damage, but scary. I wasn't allowed to get another one. Just be careful!

    We found that bicycle tubing explodes much less violently than surgical tubing. When building your own, consider (safely) filling a few innertubes to failure to get a sense of when and how they break.

    I never had any tubing explode on me in the summers that I did this and neither did any of my friends. Still, good point and just wear some goggles while filling them up.

    Sweet shirt, hopefully mine will come sometime. :)

    Looks like a lot of fun, and very easy to make... I'll have to try this -- perhaps fit a nozzle on the other end for even further distance and longer shoot times :D

    Haha funny you mention that. The originall design had an open streamer nozzle attached to the other end. Although it may seem like it, it didn't shoot as far, maybe 5 or 6 feet. We had a pretty small stream too. It lasted for a good 4 or 5 minutes, though. So it is really just a trade off. The version posted here is cheaper, too, as you only have to buy one part. Glad to see you like it.
