Dale Dougherty here giving an awesome talk on makers and their place in America (Hackerspaces included)
America was built by makers — curious, enthusiastic amateur inventors whose tinkering habit sparked whole new industries. At TED@MotorCity, MAKE magazine publisher Dale Dougherty says we’re all makers at heart, and shows cool new tools to tinker with, like Arduinos, affordable 3D printers, even DIY satellites.

There are various plans for nozzles online but I wanted something simple and a bit more elegant (if that’s possible with PVC) than what I was seeing. I also wanted my nozzles to use as few parts as possible.
Here’s what I came up with:
* 1” PVC threaded to smooth adapter
* 3/4” PVC end cap that fits inside the smooth end of the adapter
* 12, 16 or 20 ounce plastic bottle of soda. Some caps work much better than others, look for the ones with numerous thin knurls. Regular Pepsi caps are good for instance.
* PVC cement.
* 5 minute epoxy.
* A nail or non tapered toothpick to use as a trigger. It has to be long enough to go all the way through the 1” adapter and stick out on both sides.
* String to use for the remote trigger.
* Drill bit the same diameter or slightly larger than your trigger.
* 3/16” drill bit.
* Hobby knife or Dremel with a spiral cutting bit.
* 2 liter bottle of Diet Coke or Diet Pepsi.
* Package of mint Mentos
