Drop a coin onto the launching pad and spin the Vortx unit in a circular motion. This creates an immense amount of speed causing the coin to spin around and around until it finally drops to the bottom storage area. -- "The longest continuous rolling so far is 33 hours, 16 minutes." -- Challenge your skills, spin the coin back up the tunnel or spin it upside down, plus more. Instructions include a simple explanation of how it works and leads the reader into a quest for more knowledge of physics and mathematics. |
