Silk Thru Phone - Close Up Magic
Magician borrows a smart phone from spectator. He rubs the silk to the center of the screen...... In the next moment, the silk starts penetrating through the smart phone....
Eventually the silk penetrates all the way to the end!!
The smart phone is immediately returned to the spectator for examination, however, (of course) there is no slit or secret hole at all......
Super Visual yet Easy to do. Plus this miracle happens even with borrowed smart phone!
