The magician shows an ancient guillotine with a large central hole and three smaller holes. After extracting the blade from the frame, insert a zucchini in the central hole, three carrots in the three smaller holes and forcefully lower the blade. The audience will see the vegetables split perfectly in two. At this point the magician will try to do the same with the spectator's arm and three other carrots... the result? The three carrots will break in two while the spectator's arm will remain inexplicably intact.
The tool is 41 cm high, 28 cm wide and has a thickness of 3 cm. An effect that can be presented both in a serious and in a comic version.
