Rising Colours

We were talking about primary colours yesterday, and I thought we could try a little experiment with paper towel.

A and I made some coloured spots with markers on paper towel and placed it in water to see what would happen. As the paper towel sucked up the water, it took the colours with it, making them rise up the paper towel. A was amazed and excited by this.

A used markers to make more coloured spots on another piece of paper towel and placed it in some water on a plate. She let the paper towel lay flat, rather than upright. The colours spread out on the paper towel as the water was absorbed.

We also tried drawing the primary colours on top of each other before placing the paper towel in the water. The yellow rose up into the red, then both of them into the blue. Up went the water, and up went the colours, mixing together to make some orange, and purple and brown.

This was fun and easy, and I loved watching A’s eyes light up when she saw what was happening.
