My Experiment

I had four experiments and I  had to choose which one I had to do. I chose the colour changing milk experiment. I poured milk into the plate and put  4 drops of food colouring. Then I placed a cotton bud in the middle of the food colouring dot. When I placed it in the middle, it only moved a little bit. But when you dip the cotton bud in dish washing liquid, the colours spread so far apart. It was a chemical change because the dish washing liquid made the colours spread. Here are some photos I took you could try it as well 😃😁
