This captivating experiment demonstrates capillary action. The paper towels are made of fibres, which, due to their nature, can pull water upward, against the force of gravity. As the coloured water travels through the fibres, it moves from one cup to another, leading to a delightful mix of colours in the middle. It's like art and science combined! #TheDadLab #scienceisfun #scienceexperiments | TheDadLab
