Spinning Disc

Room 12 did an experiment using a spinning disc. The spinning disc is a circle with two colours on each half. Our focus was to combine two colours on a wheel and spin it as fast as possible so the colour change will be easy to observe. The colours we used were blue, red and green. With each wheel a new colour emerged.

When our circles were finished we punched two holes into the centre of the circle. We inserted a string through the circle. We turned the string until we couldn't turn it any more. We pulled the string and we noticed different colours in each of the following combinations:  blue and red made purple, green and red made yellow and blue and green made turquoise.
