This will clean the s**t out of everything.
From the submitter:
"Wife asked for a new meat grinder with electric motor. I saved some money and made one from hand-powered grinder and drill. The best part is that I was allowed to buy a new drill and leave the old one for meat grinding."
This Indonesian dentist is well aware of the fact that dental drills can be a little bit... err... intimidating. So, he created a drill that, instead of making the typical whirring and buzzing noises a drill makes, plays audio of the patient's favorite songs from an MP3 player. Nothing like a little Gangnam Style to ease the nervousness of having a whizzing metal object shoved into your mouth (no, don't even go there...).
