Try the experiment again using a different combination of primary colours or secondary colours to see whathappens. Can you add more glasses and make a rainbow? What happens if you use a different material as thebridge between the glasses?

Colours are divided into primary and secondary colours. The primary colours are red, blue, and yellow, andthese can be used to make all other colours. Secondary colours are made by mixing two of the primary colourstogether, and include orange, green, and purple. It may look like magic, but the water is moving using a process called capillary action. Capillary action is theability of a liquid to flow into narrow spaces. The water sticks more easily to the small spaces in the papertowel than it does to the other water molecules, so it is absorbed by the paper towel and can travel up andinto the other glass. This is the same way that water travels up the roots of a plant, or through your tear ductswhen you cry!
