What Does a Brain Feel Like?
By John Musico

In formaldehyde, a brain is rubbery, but its normal consistency is more like Jello. Why then, when you smack your head; “I coulda had a V8”- don’t you get immediate significant brain damage? The answer lays in an ingenious design…
Your brain is floating in fluid inside your skull. Your brain is hollow which is also filled with fluid.
Much like a raft in a pool on a cruise ship; when the ship (analogous to your head) leans one way in the ocean; the water in the swimming pool tilts the other, such that the raft (your brain) remains motionless.
