Use the Thread Genie gimmick to make a dollar bill, a business card, a playing card, or any other light objects float in mid-air!
The clear plastic cylinder contains about 18 feet of ultra strong semi-transparent micro fine thread on a reel, and has a small pin to attach it to the underside of a collar, the inside of a shirt, etc. Thread can be extended up to 5 feet and can be anchored on an object with the piece of wax that is included, and retracts back into the cylinder when released.
NOTE: Thread and mechanism are delicate; careful handling is required (this is very, very fine thread - that's what makes it "invisible"). NOT FOR BEGINNERS!
