This is Your Brain on Karo

Here are a few pictures from Lukas' science experiment today.  The current chapter is about the brain and nervous system, and the experiment is to demonstrate the benefit of the cerebrospinal fluid that surrounds our brain.

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!

That's awesome, and a great way to explain it.
