SLIME TIPS

I made one simple addition to our glow in the dark slime recipe. When I mixed the glue and water together, I added about 3  drops of blue food coloring to give this lightsaber Star Wars slime a subtle glowing blue color.

THE SCIENCE BEHIND THE HOMEMADE SLIME RECIPE

What’s the science behind the slime? The borate ions in the starch {or 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 essential to this process. Think about when you leave a gob of glue out and 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!

We added as many lightsabers as possible to decorate our Star Wars slime. Then, some of our favorite LEGO Star Wars characters joined us. 

Our easy slime recipe has taken on so many themes for season and holidays. We love LEGO and Star Wars, so it was a lot of fun for my son to mix the two together. Store your Star Wars slime in a plastic container with a loose lid to enjoy all week.

Please make sure to wash hands and surfaces thoroughly after playing with slime. It is a chemistry experiment, after all!

Most of our Star Wars slime play happened in a dim room. We would charge the slime with the lamp and play until it went dark and recharged it repeatedly. It’s not easy to get glow-in-the-dark photos, but you get the idea. It’s pretty cool, just the same.
