What better way to see how an internal combustion engine works than to be able to see all of the parts move. As you turn the crank, each of the parts move, just like the real thing. The Visible V8 Engine features moving pistons and connecting rods. A superb educational tool on the inner workings and construction of a V-8 engine.Expires Feb 15, 2011
