Pythagorean Shot Glass

Inspired by the Pythagorean Cup Wikipedia ( http://en.wikipedia.org/wiki/Pythagorean_cup ). I made this trick shot glass. Pour water (or some other liquid) in the top and it works fine. If you pour in too much and it magically drains away, thanks to SCIENCE!

See my video demonstation here: http://youtu.be/Z_eCbkFJUQ0

Instructions

1. Print the top, it's all you need for it to work. I printed the working model with 3 shells and 60% infill and I don't have any leak issues.
2. Print the bottom, to catch draining fluid and so you don't make a mess. with the same 3 shells and 60% infill.
3. HAVE FUN WITH SCIENCE!!!
