You could put it over the bottom of an upside down cup and watch it slowly flow down. Try flattening your slime into a pancake and then holding it from one edge to see what it does. As you stir the borax and glue solutions together, the mixture becomes thick. It also attaches to the popsicle stick. When you pull slowly, your slime will stretch. However if you pull quickly it will break.
Slime will slowly flow making it seem like a liquid, but it can also bounce which makes it seem a bit like a solid. The glue has long flexible molecules in it called polymers. These polymer molecules slide past each other as a liquid. Borax in water forms an ion called the borate ion. When the borax solution is added to the glue solution, the borate ions help link the long polymer molecules to each other so they cannot move and flow as easily.
When enough polymer molecules get hooked together in the right way, the glue solution changes from being very liquidy to a rubbery kind of stuff that we call slime!

He has a great video or two on Facebook regarding the safety of borax powder for slime making. Actually boric acid which is in the same boron family as borax powder is what is used in insecticides as well as eye drops.
Borax powder is laundry, some hand soaps and trace in fertilizer since it is mined through the ground. Through an intense processing borax powder can be turned into boric acid. They are however, not exactly the same. Yes, your saline needs the ingredients boric acid and sodium borate to work properly.
Depending on your location, you can also try liquid starch. I need some slime facts, I am doing a project on slime at school. I need some help. Thanks, Everest. Hi there- I want to use your liquid starch slime recipe for my first grade Halloween party—Can you tell me if one recipe is for one kid or for how many—so for a class of do I make 24 recipes? One recipe will make quite a bit of slime. One batch could easily be split ways depending on how much you want each kid to end up having.
I like the condiment size containers that hold about 2oz each! One batch usually fills about 5 of those! Feel free to email me [email protected] if you would like to talk about it more!
I know that there were many reports on the news about kids getting burns from the borax in their slime. Personally I did not get burned but my hands did feel tingly and slightly hot.
All in all it does work as an activator but I would advise to choose another activator like detergent or contact lenses solution. Sensitivity is a huge issue. However, my skin did not like laundry detergent at all and I highly advise to stay away from laundry detergent which is why we do not have a recipe for it. We use less borax than most recipes, and if you do have sensitive skin I would choose saline solution not contact lens solution.
Liquid starch is another choice. All the choices contain some form of borons. Plus you can read more science here. Slime is a neat chemistry activity that covers polymers, cross linking, and general chemistry and you can read more about slime science here. Did you making slime is science too! Neat chemistry to be exact, and you can read more here. Believe it or not, slime is actually an awesome chemistry demonstration, and I have some simple […].
This is because glue is a polymer and the liquid starch is changing the structure of that polymer as the two come together. Head over to Little Bins for Little Hands to find out more about the science of slime. Our post is great for introducing young kids to the wonderful world of polymers and contains some […]. You can read more about the simple science behind the slime here. You can learn a little bit about molecules and activators and what really happens when you combine all these slime ingredients!
