Grow A Brain - Polymer Brain Science Kit

Here's a fantastically detailed brain that grows and grows when placed in water!

Drop this polymer brain into fish bowl sized container, fill with water, and watch it grow to almost the size of a human brain in just a matter of weeks!

All you need to do is change the water every few days in order for it to reach its maximum potential.

Live out a mad scientist's dream by growing a brain inside your own laboratory or wherever your science experiments take place.
