What's with the little bench dancer?

Do you want to ask what magic it is to dance on a small bench? Magic show with fishing line and background. The magic of dancing on a small bench should first choose a place with a messy background and put a thin fishing line on the table. The thinner the fishing line, the more chaotic the background and the less conspicuous it is. Then the performer shows that the stool has no mechanical device and puts it on the fishing line, and the assistants on both sides of the fishing line will pull the stool and dance automatically.
