PRESSURE is an effect conceived by Daniel Garcia with additional insight and assistance from David Blaine magic producer Dan White.
A borrowed cell phone is held in one hand - and a balloon is inflated. The cell phone visually penetrates inside of the balloon. It is shown, then given back to the spectator with the cell phone still inside.
The result is a twisted hybrid of visual craziness: the borrowed cell phone is INSIDE of the balloon. The spectator removes it herself. There are no crazy gimmicks. Any cell phone. Any balloon. Nothing but magic.
