Heart Pump Lab

A glass 3D heart on a lab bench, pumping blood round the lungs and the body while you poke at it.

What you doStep through a single heartbeat, follow one red blood cell all the way round, change the heart rate and jam any of the four valves to watch the blood run backwards and the pressures go wrong. It's a toy that teaches you something.
