Hedgefund Piggy Bank

Hedgefund Piggy Bank

The name of this piggy bank tips you off that it isn't actually intended for children. But we think the physics lesson you might get every time you put a coin in the top is worth considering it for collecting your kid's college savings.

This bank imitates, on a much smaller scale, a hyperbolic funnel, which you may have seen in a science museum. When you start the coin spiraling at the top, gravity slowly drags it in a smaller and smaller circle with a faster and faster velocity. (If you are a science teacher or a scientist, please forgive the possibly inaccurate use of technical terms!)

At any rate, it's a bank that makes putting money in a fun experiment, or at least a mesmerizing little show.

Available for $75 from Fitzsu.
