It will seem stringy and clumpy, but that’s ok! Remove from bowl. STEP 3: Pour borax/water mixture into glue/water mixture and stir it up! You will see it come together right away. STEP 2: In the second bowl measure out about 1/2 cup of clear glue and mix with 1/2 cup of water until well mixed. 1 tsp makes a much firmer putty-like slime. If you like a firmer slime and are using white glue, we experimented with 1/2 tsp and 1 tsp. Mix this thoroughly.īORAX SLIME NOTE: We have recently tinkered with our recipe and found that for a better oozing and more stretchy slime we prefer 1/4 tsp of borax powder (if using clear glue always use 1/4 tsp). STEP 1: Dissolve 1/4 teaspoon of borax powder into 1/2 cup of warm water in one of the three bowls.

Get your slime ingredients ready, here I show you how to make slime with borax in these pictures using only clear glue but go ahead and add color and glitter if you wish! Also, you can use white glue instead. It does and you can use slime making to explore states of matter and its interactions. Can you change the density? Did you know that making slime aligns with the Next Generation Science Standards (NGSS)? We call it a Non-Newtonian fluid because it’s a little bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. As the slime forms, the tangled molecule strands are much like the clump of spaghetti! Is slime a liquid or solid? Picture the difference between wet spaghetti and leftover spaghetti the next day. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Slime is a polymer. You add the borate ions to the mixture, and it then starts to connect these long strands together. These molecules flow past one another keeping the glue in a liquid state. The glue is a polymer and is made up of long, repeating, and identical strands or molecules.
What’s slime science all about? The borate ions in the slime activator (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and form this cool stretchy substance.
We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!
