The video below explains it all, right from what you need to how to perform it. If you still don't understand how its done after watching the video, please move on to the next step
As a token of appreciation for viewing my Instructables, I have you another video I revealed, Criss Angel through glass. You can view it in the 3rd step of my instructables.Hope you like it!
Step 1: What You Will Need
1.A large cup
3.Some tissue paper ( or a sponge)
4. A bag of coins (Preferably big ones)
5. A ball of newspaper
There will be a small hole under the large cup, small enough so that your finger can fit through
How to arrange them:
Put the tissue paper in the large cup, covering the hole.Next, put the smaller cup in the large cup tightly and make sure you cover the sides.Then,take the newspaper and stuff it in the small cup. The purpose of having newpaper is to make the cup lighter, so you don't need a lot of coins for this. Next pour in the coins in, it should stay above the newspaper. Make sure its on a suitable level ,slightly below the surface of the large cup.Now, you can pour in coffee, make sure its thick enough that you cannot se the coin inside.
Step 2: How to Handle the Cup
Put your middle finger in the hole, make sure it looks like you are just supporting the cup from below, but actually one of your finger is in the hole.
Now, slowly push your finger upwards causing the smaller cup to move up without being noticed. Make sure you practice this part well. The coffee will now sip between the gap on the 2 cups. This wil create the illusion that the coffee turns to coin instantly.
Make sure you do a litle shake to make the performance more appealing and your audience won't notice that the coffee is moving down.
Have fun and enjoy!
