As I said I will be doing the milk and food coloring experiment. All you need is milk, food coloring (your choice of color) dish washing detergent and a bowl. First, all you have to do is pour some milk into your bowl, next pour some food coloring into the same bowl. The colors that I used were pink, blue and yellow. Then all you need to do is put in some detergent and watch the colors spread around the milk. Putting in the detergent I used a small paint brush so I wouldn't put too much in. This turned out to be a huge successes. I loved watching the colors change and spread all around.
