Welcome to the water-fueled salad-spinner cake box. Here's a muscle-free salad spinner that works from the power of a sink faucet and rotates your salad greens faster than the manual version no matter how much muscle you put into it. Rick Crammond based his spinner on a design invented by Nikola Tesla using his CD Turbine. The turbine combines CDs or DVDs, their spindle case (or cake box as it's sometimes called) and a bunch of magnets. Using your faucet or garden hose, you can spin your greens at 1,000 rpm, giving you superbly dry greens in seconds.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
