Mix ½ – 1 tsp borax with one cup of warm water, stir
until completely dissolved. Allow the mixture to cool.
In the other mixing bowl, add as much glue as you
like, and then add water to the mixing bowl. You’ll want to keep it at 1:1
ratio. Mix until it’s fully combined.
Time to add some fun! Add few drops of food coloring,
glitter, sparkles, or even confetti to upgrade your plain slime into that cute fancy
Pour the glue mixture into the borax mixture. Wait a
minute and see the magic happens as the mixture start to polymerize.
Prep those biceps and stir the mixture vigorously. You’ll
want to get as much of the borax combined with the glue as possible.
Once it doesn’t feel sticky, pull it out and
knead some more to get the right consistency.
Voila! Your goopy, stretchy, squishy slime is ready to

You probably didn’t put in enough water when making the
glue mixture. You might need to remake your slime (that’s where the second
bottle comes in handy!).
point #5 Science behind this
Non-Newtonian Fluids are the main concept in slime science. A polymer is a long
chain of identical, repeating molecules. The glue we used in our slime is a
tetraborate is the chemical in borax that linked the polymers in the glue
to form the putty-like material. This process is called cross-linking.
material is called Non-Newtonian Fluid which is neither a true liquid nor a
true solid material. You can pick it up like a solid but interestingly it can
flow and fill the shape of the container like the liquid does.
