Body Systems: Cardiovascular System: Heart Mold

It's probably too late to use this idea for this year, but it's always okay to start planning for next year. 

Educational Innovations (more on them coming up in the near future) makes this heart mold to be used in constructing a gelatin heart.  It includes instructions for making a hear the same size, shape, mass and color as an adult human heart. 

A little disturbing, a lot cool!


PS If you like this sort of thing, they also make a brain mold...

PPS Amazon sells a similar heart mold and brain mold.  They are less expensive, but I'm not sure how the size compares and I don't believe they include the instructions for getting the proper mass and color.
