Make:'s April Fool's 3D Printing Contest

This cup includes many tricks! If you sip out of the wrong holes then you might end up getting soaked! Enjoy!

BEST PRANK CUP EVER !!

The design relies on two printed bearings, as well as weight distribution and center of gravity to deny water to a would-be drinker.

This cup will spill all over you unless you know the trick. Hint: look at the holes.

Spin the spiral cup to unscrew it's contents and see if you can figure out how to avoid the dribble holes.

It looks pretty ... pretty useless.
