..or what to do with Lego on a rainy weekend to amuse the kids.
Lego V8 Engine
Below is a fantastic V8 Engine made from Lego. I stumbled upon this video while looking for examples of pneumatic Lego parts. The V8 is powered by compressed air and is produced by LPEpower. It is capable of running at 1500 rpm at 4 bars of pressure. Excellent!
