Description

Mercasoba is a super low-tech soap mold for card magicians to load a signed card into a transparent soap bar.

A card is selected and its face signed by a spectator. It is then returned to the deck. After shuffling and returning the deck to the card box, the spectator is invited to the kitchen / pantry where the water tap is located. The magician rinses his palm under the tap and rubs his hand with soap. He claims that the index of the card will emerge on his palm but nothing shows up. The signed card is named by the spectator and to everyone's surprise, it is found in the soap bar that the magician has just picked up a moment ago.
