In today’s experiment we have one of our volunteers, MarieJo, show us how to visualize diffusion rate. Diffusion rate can be observed by adding drops of food dye to different water solutions (hot water, cold water, water with sugar…). This phenomenon is also present in our body, when diffusing oxygen from our blood into our muscles for example. For this experiment, you will need 1 cup of hot water, 1 cup of cold water, 2 cups of water at normal temperature, 2 tablespoons of sugar and 2 different food dye colors. You can skip ahead to 1:00 to jump straight to the experiment!
