You have the Secret Genii at your command!
Place the rope into the vase. The rope is loose, but when you turn the vase upside down- the rope stays suspended inside it!
BUT WAIT- there's more! Hold the rope and let go of the vase- the vase is now suspended in midair- as if the secret Genii inside the bottle has grabbed the rope!
You can have a lot of fun with this one, as you tell the story of your secret Genii who lives inside the bottle, and will grab the rope at your command. Of course, if you hand the bottle to your spectator, the rope will not stay inside the bottle, and the bottle will fall to the floor!
Using your imagination, you can get a LOT of mileage out of this simple but AMAZING magic trick!
