We ran out of paper to paint on this week, so we tried painting some paper towel with water coloured with food colouring. We used eye droppers (bought at the chemist) to drop the coloured water onto the paper towel. It was fun to watch the colour spread out as it was soaked up by the paper towel.
We also folded the paper towel up and carefully dipped the corners into the coloured water. Once each corner was done, we unfolded the paper towel to reveal the neat patterns it had formed.
