 Hey, I have this science project for school and I really really really need help...
I need to do a real scale of a beating heart, and i need help with the pumping mechanism and with the materials I can use.. please someone help me! how can i create a machine that will make the heart beat, and how can i do a very realistic heart?
Thanks!

My first thought is to mold ballistic gel around a balloon connected to a hose...use a squeeze-bulb to pump air in and out, and manually make the heart beat. Some more project details would be nice, particularly if this is supposed to be just an external model or if you need a cutaway to show chambers, etc.
