If you turn a gear the head spins on my machine, that's why I named him Head Guy.
I found some gears and then my dad thought helped with the idea to make his head spin so now his head spins.
While I was making my machine we had a hard time putting his neck on, because we had to find the right tape. My Mom just bought some new red tape and we used that to fix the neck. I would change the arms if I wanted to change it. I would make the arms spin with the head.
