    Super Slime

    Uploaded by

    This document provides instructions for making super slime. It involves combining a borax solution with a guar gum solution and stirring until the mixture thickens. The resulting slime is described as a non-Newtonian fluid because it can behave both like a liquid and solid, flowing into containers but also holding its shape. Safety tips are included to handle the borax carefully and not eat the slime, as it is non-toxic but not food.

    Science with Zoe & Cogs - Experiment 6

    Super Slime

    What to do:
    Preparing your borax solution
    1. Label your bottle borax. 2. Add 250ml (1 cup) warm water to the bottle. 3. Add 4 slightly heaped teaspoons borax to the water. 4. Place the lid on the bottle. 5. Dissolve the Borax by shaking the bottle. 6. Add some more borax until you can dissolve no more.

    Is your slime a solid or a liquid? Actually its neither! Its what is know as a non-Newtonian fluid.

    Making your slime


    1. Add 125ml (1/2 cup) of warm water to the bowl. 2. Add 3 drops of food colouring to the water. (optional) 3. Add 1g guar gum powder (approximately teaspoon) to the water and stir until dissolved. (if it turns into a paste try again and add less guar gum!) 4. Add 2 teaspoons of glycerine/ glycerol to the guar gum solution and stir. 5. While stirring, slowly add the borax solution to the guar gum solution, a few squirts of your bottle at a time. Continue stirring until it thickens and you can lift the slime up with your spoon/popstick. 6. For different degrees of sliminess, experiment with different amounts of borax solution and guar gum.

    Ingredients

    Borax powder (laundry section of supermarket) Guar gum powder (health food stores) Glycerol/glycerine (pharmacy or supermarket) Food colouring (optional) Warm water

    Equipment

    Measuring jug 2 teaspoons Popstick for stirring Plastic bottle (plastic squeeze sauce bottle is ideal) Mixing bowl Jar or ziplock bag ( to store your slime)

    Super Slime

    What else do you see?

    Use this space to write about, and draw anything else you noticed while doing this experiment.

    When you add the borax solution to the guar gum solution it joins together the dissolved guar gum molecules. Scientists call this joining together cross-linking. The more borax you add the firmer the slime becomes. Eventually all the molecules are stuck together and the water is trapped inside. But is your slime a solid or a liquid? Sometimes it behaves like a liquid just like when it flows to take the shape of the container youve placed it in. Other times it acts like a solid when it sits like a blob in your hand. So which is it? Actually it is neither, and scientists have given substances like these a special name a non-Newtonian fluid. IMPORTANT STUFF Handle the borax with care. Please read the safety instructions on the container it came in. Once the slime itself is made you can safely play with it with bare hands. But wash your hands after playing with it. Slime is not a food so dont eat it. Making and playing with slime can be extremely messy! Make sure you are wearing old clothes and be careful around furniture and carpet! Store your slime in a jar or ziplock bag in the fridge.
