Oh, I see, cotton candy becomes rotten candy with two letters changed. In my twisted mind, and evil clown would be digging down in the back of his pants and pulling out chocolates. 
YOU ARE NEVER TOO OLD lemonade!I'mbadash, it was easy. Used a reindeer motor, drilled a hole in the pan, attached with screws. It took a while to sync the position of the arm with the movement to make it stay right, but then I am a 65 year old woman, thus most things take me longer. You should definitely try. Thanks.
I don't have any way to make a video, but it is quite simple. I attached a rod and a cup (the top of a fabric softener bottle) to a reindeer motor (bolted to the bottom of the pan) which travels in a circular path. The cotton candy stick sits in the cup, the stick is wired to his hand, thus moving around. I am technically challenged, but not mechanically.How about a video to show the action?
