Introduction: "Pentrifuge"

After viewing the jenga pistol, I wandered over to some other videos by the same guy and found one that was fun- a device to spin a dry ballpoint pen using a hand crank in the hopes to make it work again, with the help of centrifugal force. My gear ratio is nothing like his, but it still speeds the pentrifuge to be about three times that of your hand motion. I ran out of pieces, but it works and it's kinda cool haha.

lol, does it hurt if you get slapped by it?

Actually it kind of does, if you crank hard enough. I rushed the construction and it hit my hand a few times >.>

lol :p

Did you hit yourself in the face with it? :)

I thought about removing the brace and letting the centrifuge fly off, but then I realized that, knowing my luck, I'd probably take my own eye out :P but I haven't disasembled it yet, and I'm really bored...hmmmm...
