The shell of M and M's are made from sugar and different coloured dyes are added. When you add warm water to them the shells start to dissolve and the dyes start to mix together. This is a similar activity to the one using candy canes. You may also like to look at the paper chromatography activity to learn more about how colours mix and separate.
The first thing that we are going to do is arrange the M and M’s in a circle around the edge of the plate.
We are now going to pour some warm water into the middle of the plate. The water will move outwards until it reaches your circle of m and m’s. When it does it will start to dissolve the sugar coating
You should start to see the different colours from the sugar coating of the m and m’s moving towards the centre of the plate.
The different dye's will then start mixing together.
You may like to experiment with different colour combinations to see how the different dyes mix together
The video tutorial for this activity is available on the Surrey Libraries Facebook Page
