A Benham disc is a black and white record that produces the illusion of seeing other colours. When rotating this disc with the right speed, the pattern appears to have colored rings. You see "colours" because different colour receptors in your eyes react at different speeds, depending on your sensitivity.

This activity comes under the program #cienciavivaathome. From the kitchen to the bathroom, even walking through the garage, no room was left out: after all, science is everywhere!
