A WHAT? It is the weirdest and funniest thing you can imagine!
The 5 millimeter hole in the middle of the wooden body of the “horse” is larger than the 3.5 millimeter steel wire of the pole, and that makes it “hang-up” by FRICTION on the pole. Just slide it to the top and it will stay there. Now move the head a little up, it will bend the spring, let go and the “robot” slithers and slides in small steps down the pole, the ribbons swaying, the head bobbing. The robot itself is like a lever with a spring and the friction makes it go in steps, one little step down, stop, then down again.
The magic rocking horse is finished. Move it to the top of the pole and let it slide down, if it sticks a little that is good, it will start to rock down the pole, shaking its head, it is really funny and your friends will be endlessly entertained … IF it does not hang still at the top make the pole a little rough with some emery paper or clean it with a wet towel. DO NOT GREASE THE POLE.
