Incredible diffusion of paint
To take this picture, I prepared a 50-liter tank and filled it with water. I also have blue and orange paints. Use two small needles to suck up enough paint and quickly squeeze both into the water at the same time. After only one or two minutes, the paint and water begin to blend. The physical phenomenon demonstrated in this experiment is diffusion. Diffusion is when different substances come into contact with each other and move into each other. In experiments, different colors of pigments enter water and mix with each other. The cause of this phenomenon is the constant exchange of liquids caused by the irregular movement of molecules. The initial experiment was done under room temperature. We did several more experiments and found that the higher the water temperature, the faster the pigment spread.
