Junior infants had great fun making jelly hands and seeing how the materials used turn from a liquid to a jelly mould.
Seeing the magic behind this chemical reaction.
How it works:
Milk is made up of mostly water but it does contain vitamins, minerals, proteins and small droplets of fat. The fat and proteins are super sensitive to changes in the milk and so when the dishwashing liquid is added a chemical reaction occurs.
The soap and fat work hard to join together, which causes the movement. When food colouring is added we are able to witness this chemical reaction occurring.
