HOW DOES IT WORK
The blades in the disks are angled to resemble helicopter blades. When the disk is given a quick push off the screw-like launching stick, the mechanical force launches it high into the air so it achieves flight. Leonardo da Vinci speculated that men could actually take to the skies on similar screw-like mechanisms.
HOW TO PLAY
Hold the spiral stick by the flat handle at the base and thread the collar onto the stick with the wide brim facing up. Thread the propeller onto the stick through the thin slot in the middle of the propeller and let it wind down. Holding the stick upright and clasping the collar with your fingers, push the collar upwards in a fast motion and watch the propeller launch off the stick and fly!</p>
