Homemade slime is a gloopy variation of playdough and silly putty, easily made from common household ingredients. Making homemade slime is an easy and fun sort of science experiment to keep the kids busy. Once you’ve mastered the basic technique, there’s no limit to the ideas you can come up with together.

There are lots of recipes for slime. Which one you choose depends on the ingredients you have and the type of slime you want. This is a simple, reliable recipe that produces classic slime.


(NOTE: This is for a large batch. You can divide the amounts by 3 and make a smaller batch, especially if you want to test the recipe first. The contact solution binds the ingredients together.)

Sensory Experiments for Slime

Making slime is also a great activity for sensory stimulation! Here are a few fun experiments.

Add Texture:

Add gems, beads, glitter, or poly beads for an even more exciting sensory experience! Choose different colours and shapes to create a unique feeling and help with tactile stimulation. Also, if you use clear glue instead of white, you can see the items and not just feel them! TIP: It’s easiest to add the items before you mix in the saline solution.

Add Shapes:

You can give your slime different shapes using cookie cutters! We made several different colors of slime and added some shapes to it, like hearts and circles. If you don’t press down completely, the shapes fade after awhile. Have fun with it and play around with the designs!slime sensory activity

Testing Ingredients:

Experiment with different amounts of each ingredient. Ask kids to answer questions as you go. What happens when you add more than 2 tablespoons of saline solution? Does adding more or less baking soda make a difference in how the slime feels?

Mixing Colors:

The great thing about slime is you can use any colours you want! To create a marble effect, first, complete all 5 steps with one colour. Then, choose another colour to make and during step 5 as you add the saline solution, knead the finished slime into it. We did this with pink and blue!marbled slime

PLEASE NOTE: Adult supervision is recommended for this activity. Although contact lens saline solution is a safer option than Borax, it does still contain Boric Acid, and should not be ingested.
