Slime and Sugar Crystals

Today we certainly had fun in science!

We made slime and sugar crystals.


Slime:
Combine 1 teaspoon borax (you can get this in the cleaning section of the supermarket) and 1 cup of water in a bowl.
Combine 1/2 cup PVA glue and 1/2 cup water in another bowl.
Add food colouring to the PVA mixture.
Pour the PVA mixture into the borax mixture.
Knead the slime - as you continue to knead it, it will become less sticky and more firm.
Tip out the remaining water.

Store in an air tight container in the fridge. It lasts about a month.



Sugar Crystals:
Combine 2 - 3 cups of sugar and 1 cup water in a saucepan.
Stir over low heat until the sugar has dissolved.
Add some food colouring for fun.
Pour into a glass jar.
Use a peg to hold a wooden chopstick in the solution - don't let it touch the sides or the bottom of the jar.
Leave the jar undisturbed for about a week.
