Children's Science Experiment| How to make slime

Before you begin:


Make sure that you’re wearing protective clothing and working in an area where you can clean the ingredients easily. Let’s begin…

Ingredients and equipment

  • A plastic cup
  • PVA Glue ( Found in any good craft shop or even some supermarkets)
  • A bowl
  • A tablespoon
  • Liquid laundry detergent
  • Liquid food colouring (optional)

Step 1.  Measure 1/2 cup of the PVA glue and 2 drops of food colouring into a bowl.

Exact measurements are not that important. Just try and get it close.

Step 2.  Add a tablespoon of liquid laundry detergent.

You can use any type of liquid detergent. Again, just estimate the amount.

Now the fun part…

Step 3. Using the same tablespoon, stir well.

You will notice that the liquid starts to ‘clump’ together making a nice gooey mixture – slime!

Step 4. Clean up your area and equipment.

Step 5. Enjoy your slime!

This slime will last for several days and when you finish playing with your it, you can place it into a grip-seal bag and store it in the fridge for future use!

Important! DO NOT eat or put on clothing or your carpet! In case of accidental contact with either, just use a damp cloth, a little soapy water and gently rub it. This can be hard to remove if it dries so you need to act fast.

Did your slime work? Was is easy to find the ingredients? Was is easy to follow the steps? How long did you keep the slime for? If you keep the slime exposed to air, what happens after one day?
