We put an egg in a tupperware without water and ran around and threw it down. Splat! The egg broke inside the tupperware. (This is to show what would happen to our brain without the fluid that surrounds it.) Next, we put in another egg and filled the tupperware with water. We had to try really, really hard this time to even crack the egg inside the tupperware, demonstrating how well the fluid that surrounds our brains protects our brains and how well God designed this part of our bodies.
