Seep by Peter Loughran

The performer borrows 2 playing cards (no force required) and asks the spectator to fold one card in half long ways, and to fold the other card in half sideways. The performer then places the first card folded long ways inside the card folded sideways. Both cards can be seen nested together, yet something strange begins to happen the card folded long ways begins to melt and seep right through the center of the other folded card. Both cards are then immediately opened up to show they are still completely intact. The two cards are then handed out for examination and for the spectator to keep.
