I spoke to some one about this who used to host dream catcher. He said it’s not motorised but is weighted, and the flicker thing had been taken off the wheel which you can see in the video, it’s not actually touching the wheel. He said due to the weight, if the flicker isn’t on the wheel can keep spinning.
Don’t know if he told me this because evolution had an agreement with him or if it’s the truth, but usually he can’t lie for shit, and it looked like he was being honest with me.
