CHEMISTRY
Science Behind the Experiment
How does the slime-making experiment work?
The slime-making experiment involves mixing a few simple ingredients, such as glue and a slime activator (commonly borax or liquid starch). The glue contains a polymer called polyvinyl acetate, which gives slime its stretchy and gooey texture. The slime activator helps to crosslink and bond the polymer molecules together, forming the slime.
​
Why does the slime feel slimy and stretchy?
The slimy and stretchy properties of slime are due to the unique behavior of polymers. Polymers are long chains of repeating molecules. In slime, the polymer chains slide past each other when it is stretched or squished, giving it its stretchy and slimy feel. The more the polymer chains can slide, the stretchier the slime becomes.
​
Can different ingredients be used to make slime?
Absolutely! There are various recipes to make slime using different ingredients. For example, instead of borax or liquid starch, you can use contact lens solution (which we do) or baking soda mixed with water as the slime activator. Experimenting with different ingredients can result in slimes with different textures, colors, and even scents, adding to the fun and creativity of the slime-making experience.
What You Will Learn
In the slime-making experiment, you'll dive into a world of squishy and stretchy fun. By following simple steps and using everyday ingredients like glue and a slime activator, you'll unlock the secrets of creating your very own slime. Through this hands-on experience, you'll discover the fascinating properties of polymers and witness firsthand how they contribute to the slimy texture and stretchiness of slime. Let your creativity run wild as you unleash your inner slime scientist and engage in a sensory adventure that will leave you captivated and entertained.

Supplies
-
Clear or white school glue
-
Contact solution (containing sodium borate and boric acid) OR laundry detergent (containing borax)
-
Food coloring (optional for colored slime)
-
Mixing bowl and spoon
Steps
Step 1
Start by pouring a generous amount of clear or white school glue into a mixing bowl. You can adjust the quantity depending on how much slime you want to make.
Step 2
If you want colored slime, add a few drops of food coloring to the glue in the bowl. Mix it well to distribute the color evenly.
Step 3
Gradually add liquid starch (or borax-containing laundry detergent) to the glue while stirring continuously. Keep adding and stirring until the slime starts to form and pulls away from the bowl's sides.
Step 4
Once the slime begins to take shape, take it out of the bowl and knead it with your hands. Continue kneading until the slime becomes less sticky and more stretchy and gooey. Now, your slime is ready to play with!
