Colour spinners

We have been learning lots about light and colours.
We were able to split the sunlight into the 7 colours of the rainbow.
We were wondering what happens when you spin colours very quickly.
Do the colours mix or stay the same?
What colour will red and blue become?
How about red and yellow?
How about all the colours of the rainbow?
We made our own colour wheels, guessed what colours they would make if we spun then, and then we spun them to see if we were right.  We used a small motor, 2 wires and a battery so that the wheels spun really fast.
Look at our results:

We took videos of what colours we can make with our colour spinners.
