| You present your audience with a heavy (approx. 620 g!) security padlock and a jar containing five keys with different colored markings. But you announce that only one key actually fits the lock. Four spectators then take turns choosing one key each from the jar, leaving one for you. The spectators are informed that they can swap keys as they wish, including with your key! Well, no matter how often a key is swapped with another, in the end it turns out that only the key in your hand opens the lock... Height of the lock above the shackle: approx. 95 mm, weight approx. 620 g. With German instructions! |
