Tactile illusion wire mesh : Velvet Hands

VelvetHands.jpg
This object is just a wire mesh. But once you hold it between your both hands and rub it, you'll feel it's like velvet. This is a tactile illusion which is caused by brain.
I found this item in Sony ExploraScience. This is fantastic! You can't understand till you actually touch it.

EDIT
