Rotary drawing machine

Children's fun that even an adult can stick to. It is easiest to use a cooler from a computer for rotation; its power is quite enough. Power may well serve as a USB connector. You can consider the option with a motor and battery. A clean sheet is attached to double-sided tape or simply lies on a rotating platform.

For drawings it is better to use new markers, so as not to make a strong pressure, which will interfere with the rotation.
