You have 2 rubber bands. One on the index finger and one on your ring finger. Take bottom part of the top one and put it under the top part of the bottom one. Bring that one back up. and put your middle fingers in that hole and when you push the rubber band down into it. let go of one of your middle fingers. If you wnat to put them back to normal you just let go of the other finger but don't let the audience notice you letting go of the rubber bands
