LETS GROW A RAINBOW! Science behind it. The water moves up the paper towels through a process called capillary action. The paper towel is made from fibers and the water is able to travel through the gaps in the fibers. The water is able to move upward against gravity because of the attractive forces between the water and the fibers in the paper towel.Tips for growing your Rainbow! 🌈 Use washable markersColor the ends nicely to make it workKeep the water cups close together- it makes the rainbow

Watch water ‘walk’ across paper towels and mix colours in this mesmerizing rainbow experiment! All you need are cups, water, food colouring, and paper towels. The Science 🌈 This experiment demonstrates capillary action. Water moves up the tiny gaps between the fibers of the paper towel due to adhesion (water sticking to the towel) and cohesion (water molecules sticking to each other). The coloured water travels from one cup to another, mixing to create new colours along the way! #DIY #rainbow #
