We did this nice activity as part of our science lesson. The children absolutely loved this, and we actually did it over and over again. They even liked the final result – when you mix all the colors together, it turns muddy brown!
First, you need to gather some milk, food coloring, cotton swabs, and dish washing liquid. Then begin by pouring the milk into a wide, shallow container.
Next, carefully add drops of food color in strategic places around your dish of milk.
Add the drops carefully so they don’t splatter or splash around the dish.
Once you have added the food color – then dip the end of a cotton swab into the dish liquid.
Then touch the dish liquid covered end of the cotton swab to one of the colors of dots. We started off with one child going at a time but then we tried letting three children go at the same time because once the soap gets into the milk, the color explosion starts to lose it’s flair!
When the soapy end of the cotton swab hits the food color dot in the milk – it spreads out quickly making the color look like it is exploding out. It is a very cool effect to watch.
Once the initial color explosion occurs, we encouraged the children to use their cotton swab to swirl the colors around some more by gently stirring the colors around.
