NightHawkInLight built a homebrew mini-sandblaster that’s powerful enough to cut glass. With the help of some electrical tape and paraffin wax, he shows how to cut a perfect helix shape out of a test tube. If you plan on trying to DIY, be sure to follow his recommended safety precautions.
There’s something so satisfying about restoring rusty old objects. This particular item – a gigantic cigarette lighter – is definitely one of the stranger things we’ve seen brought back to life. Sit back and relax as TysyTube takes the beast apart, cleans it up, and makes it good as new. Sandblasting is magic!
