Pour water in to your ice cube tray.
Lay the string in and out of each of the ice cube cups. This can be a bit tricky – if it keeps floating up you may need to weigh the string down or angle it to stay in.
You could achieve this same effect by placing a number of vessels closely together and draping the string from one to another.
Leave your trays outside to freeze, if it’s cold enough, or pop them in the freezer.
Push your ice cubes out – they should hang together in a string.
Make a loop at one end of your string, to hang in a tree or bush, or drape it like tinsel.
Take it further
Place natural materials in the water before freezing or pop in a small toy.
Try different sizes or different-shaped ice cube trays.
Instead of ice cube trays try placing a number of vessels closely together and draping the string from one to another. Experiment with different sizes and shapes.
Instead of ice cube trays make different shapes using clay, plasticine or similar mouldable material. Mould into any shape, ensuring it will hold the water, i.e. a star, then lay your string through the water, and freeze.
Try a few drops of food colouring in the water – what happens to the ice?
Do this activity in summer, using a freezer, and see how fast your strings of ice melt.
