Only you know its secret. The magician shows that you can catch a plastic hook on a rubber band that is at the end of the Red Tube. The Hook is partially removed and shown to snap all the way back proving the Hook and rubber band have been linked. As soon as your spectator tries the hook and rubber band are unhooked and no matter how hard they try the spectator is unable to link the hook and rubber band. You are able to do it without any struggle. A funny pocket puzzle to share with kids and adults! (AKA Red Snapper, Snapper Puzzle, Oh Snap!)
