The Synthetic Heart: A silicone heart that helps people visualize how the heart works.

The Synthetic Heart  is a silicone replica of a human heart that shows how a heart beats. Two syringes inflate and deflate the heart with fake blood to show the left and right sides of the heart beating.  The user will pump one side and then the other to get the beating motion. The heart is designed to be used in the classroom, as a teaching method for kinetic learners. One hope is that when people have a better understanding of how their body functions, they will take their health more seriously.
