Tireless Rings

Exploration Stage: Laboratory
From: Isabelle
Description: It's not difficult to make a clock with hands go in the opposite direction. I'm still not convinced that the City has revealed the real Laboratory of Time to us. We need to look for something truly unusual: a familiar item that would violate the usual order of things... for example, that acts against the laws of physics. Can you find something like that among all these devices?
Completed: Newton's Cradle, which never stops! Wonderful. That's just what I had in mind Just look at it! could the laboratory's owner have invented this legendary perpetual motion device? But how was he able to overcome the law of energy consevation?
