Science of Slime – How Chemistry Affects Physical Properties of Slime If you encounter issues in this science fair project, be sure to reference back to that post. In that guide, we outline various slime recipes and walk through how to make slime. Now, for an easy to read, step-by-step guide about making slime, please be sure to look at our How to Make Slime: The Ultimate Guide post. To be honest, there are truly a TON of directions you can go with this project and the fact that it can be completed in a weekend makes it a great last minute science fair project! But first, we delve more into the science behind slime.

Science of Slime – How Chemistry Affects Physical Properties of Slime.

I've got a YouTube video of the slime showing what you will get if you use glue gel rather than white glue.

Avoid magnetic slime for very young children, because it contains iron and there's a risk they might eat it. You can even make magnetic slime by adding some iron oxide powder as an ingredient. You can add a bit of color theory by dividing the slime into two or more chunks, coloring them differently, and watching how they mix. Mix in a few drops of fragrance oil to make the slime smell good. Add pigment powder to add color or to make the slime glow under a black light or in the dark. Add tiny polystyrene beads to make the slime more like floam. The cross-linking that holds the polymer together also helps slime hold mix-ins.

Feel free to jazz up the basic slime recipe.

If you used food coloring, you may need bleach to remove the color. Remove dried slime after soaking with water. Don't feel bad if a bit of slime falls into the garden.

While boron in borax isn't considered an essential nutrient for humans, it actually is an important element for plants.

Although it isn't especially toxic, it is not good for you either! Similarly, don't let your pets eat the slime. If borax is a problem, consider making slime using a truly borax-free recipe. Don't believe internet tales that 'contact solution slime' is borax-free slime! It's not. Contact lens solution is buffered with sodium borate, so it's basically a pre-made mixture of the key slime ingredients.

If you can't find borax, you can substitute contact lens solution for the borax and water solution.

If you use a translucent glue, you get translucent slime. If you use white glue, you get opaque slime. You may also make slime using the clear or translucent school glue.

Use white glue, such as Elmer's brand.
