The JOL Levitation Device was a gag effect produced by Jerry many, many years ago and lost to time. Fortunately, we managed to track one down and have it brought back to life!
The idea is that you place the small purse looking object (The Levitation Device) on a table or give it to a spectator and tell them that it's levitation device. Of course curiosity will get the better of them and when they open it up a small device inside it engages and produces a loud bang. They will of course jump at the noise and you then get to tell them "See ....it made you levitate!". It's a great little gag that takes up virtually no space in your pocket. It does of course use caps and we include a few with it to get you started and we do sell more or you can pick them up online or in local toy shops.
