A bit of fun and a great science experiement for children to watch over serveral days whilst off school. Easily able to expand this activity with making different colours, drawing them, having a competition of whose grows the largest. And plenty of questions to ask the children about how they think this process happens. Just be careful as mixture gets extremely hot!!
- 3 cups granulated sugar
- Food colouring
- Pipe cleaners
- 1/2 cup water
- Tall glass
How to make a crystal:
- Put the sugar and water together in a pan and boil until the sugar dissolves.
- Add the food colouring
- Let mixture cool slightly. Whilst letting it cool, wrap two pipe cleaner ends around a spoon handle so that the rest of the pipe cleaner hangs down. Fit near enough to each other that the both fit into the glass but still with some space between them.
- Poor mixture into emtpy glass and then put the pipe cleaner into mixture. It should come most of the way up the pipe cleaner.
- Leave for two days and watch how the mixture crystalises around the pipe cleaner. The longer you leave it the harder and more real it will look.
