Algodoo

This is my first upload. This is a water pump powered by a piston. It will only work in Algodoo, because it needs the (semi) incompressible water to work.

This is kind of a work in progress, because it barely works. I know it could use some kind of valve on the right side, but every design I tried made it worse.

If anybody has ideas on how to improve it, I'm open to suggestions.
