You paying attention Redenbacher? Those daring kids at Instructables
have created the USB Popcorn Maker from a high intensity heater light, aluminum cup, and mason jar. Add oil, non-Linux kernels, and salt and you're ready to cozy-up in an uncomfortable three-some with the Wachowski Brothers. Unfortunately, the video posted after the break jump-cuts between USB attachment and the first corn kaboom. But given the 5V USB source, you'll likely need plenty of time to get the oil boiling. Then again, nobody said this was practical.
