How does two different colour change in one spinning dis. when two colors are on a spinning dis and spin it really fast the two colors will form a different colour for example red and blue will make purple if you spin the spinning wheal really fast if your spinning it slow the colour wont show. and make sure that the two colors are colored darkly so the colors a mixed darkly and can be clear to see a make sure that the sped limit of the spinning is fast enough.
