How to Make a levitating card
To levitate a playing card you will need an ordinary playing card, scotch or clear tape, a pair of scissors, white paper and some string or yarn. First, measure the yarn by holding it up to your ear and cut the yarn at the desired level. Then, place the yarn to the white paper and separate it until you pull one thin thread from the yarn. Set the thread on the white piece of paper. Tape both ends of the thread. Tape the thread to the card. Tape the other end of the thread to your ear. You can then spin the card and move it up and down by moving your head.
