Well, it is the school holidays and the boys have been extremely good with hardly any fights or bickering - LOL!!
My 7 year old, Max, did a few experiments at school and wanted to do these at home.
This one is with a bowl of milk, a few stratigically placed drops of food colouring and then the special ingredient - dishwashing liquid.
It was quite facinating to watch the colours swirl around and mix together.
I may do a few other experiments with them in the next week.
