Easy Science Experiments For Kids: How to make slime

How can I make a simple slime experiment? Well, I cheated a little, by buying a make-your-own-slime-kit in the store. That is not a must though, since it is quite easy to make your own slime with stuff you will likely find in your home, like hobby glue (Elmer’s glue), shaving foam, and lens solution.

Always remember to start the experiment with a hypothesis, what do you think will happen?

Instructions for parents: Read this first.

Material included in the make-your-own-slime kit:

  • Polyvinyl alcohol (PVA) and Borax.

Additional things you will need:

  • A glass.

How to make slime:

  1. Read and follow the slime-kit instructions.
  2. The longer time the slime gets to mix together, the better it will be. If you want more slimy constancy, then add some water.
  3. Keep the slime in a plastic bag so it lasts a long time.

If you already have hobby glue (Elmer’s glue), shaving foam, and lens solution at home, and don’t want to buy a ready kit in the store, then check out the video below.


The polyvinyl alcohol (PVA) is a long molecular chain. Borax reacts with the PVA so that they are connected to giant molecules. It gives the slimy its tough, viscous properties. Just get your hands into it and you will feel it.

Safety first:

As with any work with chemicals, it is good to wash your hands every time, even though these materials are sold as a toy. Washing of benches and clothes can be done with water. The gel is harmless, but must never be eaten or left in such a way that others can be tempted to do so.
