brb, I need to go find a rubber hand and try this on my friends.
I've seen this experiment before but setting it up on the boardwalk is an interesting idea.
Psychology can be interesting.
Funny thing was that before they got to the surprise I was thinking "they should smash the hand with a hammer." lol
This is actually the same method used to cure Phantom Limb syndrome sufferers. Amputees often get tremendous pain over time in limbs that they no longer have - untreatable pain, because the brain is "stuck" believing the missing limb is still suffering.
In that case though they use a mirror to create the illusion of the missing limb as a reflection of the other one that's still present. Most famously seen in an episode of Dr. House :)
love seeing something new
