This week my friend and I are permanently working on a science experiment called Colour Changing.
Basically you have to use a strong cardboard and draw three perfect circles and then colour them in. When you finish the drawing it won't spin itself so you have to use a one meter string.
At this point you are ready. All you have to do is spin the circle as fast as you can or the experiment will sadly fail.
If you achieve your a spinning 90% it will work. It depends on how you let it go. If you let go in a right direction it will work but if you do it in a wrong way don't even try. When you finish you will see the result of the changing colour.
