In this tutorial, we learn how to levitate any object. You will need: four batteries, two empty cans, playing card, and a ball of tin foil to do this trick. To start, you will need to first tape two of the same batteries on the side of each of the cans. Then place the cans on opposite sides of the table from each other. After this, bend the playing card so it stands up on the side. Then, roll a small ball of foil up and place it on top. From here, you should be able to lift the cans up and the card will lift up to! If it doesn't work try again and re-tape the batteries.
