We got tissue paper, cups with a little water in them, and markers. We made spots with the marker fairly near (but not at) the end of the tissue. We put the tissue into a cup with a little water. What happened?
The tissue absorbed the water and pulled the marker dye with it. We could see the colours racing, and we could see what colours are made from other colours. We saw purple (red and blue), green (blue and yellow), orange (yellow and red) and brown (red, yellow and blue).
