In this experiment, our brain is represented by one chicken egg. Lukas put the real egg inside a plastic egg, which represents our skull.
Drop the brain in a skull, without cerebrospinal fluid, into the sink.
There it goes!
Hmmm. The brain didn't survive that fall so well!
New brain, now surrounded with cerebrospinal fluid, or Karo syrup.
Here's a brain in a skull that is well insulated!
There is goes again!
This brain survived the fall without a crack.
Just a little sticky!
