Borrow any smart phone from anyone. Show an ordinary red silk. Place one end of the silk onto the screen of the borrowed phone. Remove your hand and one end of the silk is now seen to be penetrated inside the phone. Your hand is completely empty, the silk is hanging by itself with one end that went inside the middle of the borrowed phone.
Now your one hand is gripping the phone just by the fingers, and your free hand starts pulling the silk from the back of the phone. The silk from the front is clearly seen going through the middle of the phone until it completely comes out of the other side. The screen can be seen to be completely intact with no hole in it. The phone is shown clearly, slowly, front and back that it is completely normal without any damage, and immediately returned to the owner.
