How does a rotating tree stand work?!


I just can’t wrap my head around it. I need answers!

In: Technology

The tree sits in a socket, and a little electric motor turns it around. If you’ve ever used an electric hand mixer, imagine turning it upside down – the removable mixer blades are the tree.

Imagine a normal outlet + plug. A pair of metal rods/ plates transfers electricity by being in contact with another pair of metal plates. Now make each plate a large ring instead, so they’re two circles with the same center point. Now they can rotate against each other without losing contact. That’s how a rotating tree transfers power from the base to the tree.
