The magician displays a small bottle and a rope.
 
The rope is inserted through the neck of the bottle, and—amazingly—the bottle clings tightly and will not fall, no matter how hard you shake or swing it. 
 
CONDITION NOTES:  A very nice example considering its age. The bottle shows some paint wear and loss, mostly around the neck area, but still presents well. The box remains intact and in fair condition, with expected age-related discoloration.
