Colours from black and white? Say it ain’t so!

We had half a class the other day so we just played around with some equipment left lying about.

One such piece was a cardboard disc with black circles and shapes on a white background. If you spin it quickly you get to see coloured circles! It’s mad I tell you.

Only thing is, because it’s got to be a psychological effect it doesn’t get picked up on the camera.

Hates that.
