Background

The ‘Slime Monster’ comes alive in this experiment based around polymers.

‘Ploy’ means many and ‘mer’ means ‘unit’. Therefore the word polymer literally means ‘many units’. We will be using a polymer (guar gum) and using another chemical to link the long guar gum polymers together to make a ‘gel’. We will see how adding different amounts of glycerine can change the properties of our ‘Swamp Slim’.

Measure out 10.0g of Guar Gum, 10.0g of glycerine and 10.0g of Borax using a balance.

Measure out 1.0L of warm to hot water in a measuring jug and place into a large bucket. (adult help needed if hot water used).

Pour the glycerine and food colouring into the water and stir.

VERY slowly, tap the guar gum and add to water while stirring. You may need to use a mixer to ensure it is all dissolved.

The guar gum should be nice and thick. You may leave it cool for 20-30min while you make up the Borax solution by dissolving it in some warm water.

4

Add the Borax slowly while mixing with fingers.

5

You will notice it start to thicken. The more borax you add, the thicker it becomes. Stop when you reach a thickness you feel your swamp slime is BEST.

6

Play with your slime. Wash your hands after you play with it and place in a container.

It should last for a while, but will start to grow fungus over period of time, so throw it in the bin and make more.
