Usage method: An ordinary glass of water (self-contained) + a normal coin (self-contained). These are two things that are easy to find in life. Maybe your friends don't even know what you're going to do when you take them out. It was at this time that your magic began. Ask the viewer to pick one of the coins at random, and then you grab a coin into your hand, and there's a coin left in the cup! You will hold the coin hand slowly close to the cup, in a moment your coin has penetrated into the cup. Classic close - up magic. Through magic. Simple and easy to learn, the effect is extraordinary. Notes: 1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 2. Please allow 1-3cm measuring deviation due to manual measurement. Packages: 1 x Coin Penetrates Cup
