THE SCIENCE BEHIND THE HOMEMADE SLIME RECIPE
What’s the science behind the slime? The borate ions in the slime activator {sodium borate, borax powder, or boric acid} mixes with the PVA {polyvinyl-acetate} glue and forms this cool stretchy substance. This is called cross linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state.
The addition of water is important to this process. Think about when you leave a gob of glue out, and you find it hard and rubbery the next day.
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and is thicker and rubberier like slime!

What if that particular liquid starch isn’t available in your area or on amazon?
littlebins says
Sta-flo is another common brand for liquid starch that works fine. If you don’t have access to any, try it with our saline solution slime recipe too.

How much will one batch make? I have 25 kids per classroom and each need some to work with.
