Great for students of any age! The Brain Mold is useful in anatomy, biology, and injury prevention classes -- even just for fun on Halloween! It can be made to have the same color, size, mass and consistency of a human brain. Instructions and suggested lesson plans included.REINFORCE THE IMPORTANCE OF HELMETS. Place the gelatin brain mold in a bike helmet and let it drop to the floor. Do it again without the helmet. This is your brain with a helmet and this is your brain without one! Any questions??
