How to Make Sand Slime for Beginners
Read on to see how to make the very best sand slime and engage the creativity of your students.
If you’re curious about how slime is made, it’ is because making slime is a chemical reaction! When a cup of white glue mixes with a cup of liquid starch, it creates a chemical reaction, which you can read more about below.
Since this sandy color slime does contain borax, if your kids have a borax sensitivity, you may want to try our baking soda slime instead. You may also want to try these summer slime recipes.
Sand Slime Science
Slime is made when borate ions from boric acid in the laundry starch mix with the polymer chains in the white school glue (you can also use clear school glue), creating strong, but flexible bonds between the molecules in the glue and sodium borate.
This is the same process that happens when flexible plastic is made, just in a slightly different format.
What Happens When You Add Sand to Slime?
It may seem like adding sand to slime would make the slime more solid and less slimy, but in fact, the opposite happens!
The answer lies in the surface tension of the water in the slime. The water molecules on top of the liquid mass are attracted to each other and form a thin layer.
When you add sand to slime, it pushes through the existing water molecules and creates new bubbles of water that are also attracted to each other.
This leads to a decrease in surface tension and an increase in volume, which retains the slippery nature of slime.
How Do You Fix Sandy Slime?
If this is your first time making slime, you should follow along with our slime troubleshooting guide.
If you don’t want to waste a lot of ingredients, try mixing up a small batch first to make sure you won’t have to tweak it before you make the larger version.
If you find that your slime has become ruined with hair or debris, you can still fix your sand slime!
Soak the sand slime in a solution of water and detergent and then rinse with water.
Put the sand slime back into its container and add more borax or baking soda to remove any stickiness that emerged during the washing process.
How Do You Make Sand Slime Not Sticky?
Sand itself will go a long way toward producing a less-sticky slime. The molecules in the slime stick to the sand rather than sticking to carpet or clothing.
But if you find your slime is a bit too sticky, you can add baking soda for additional texture or add a little more borax solution or laundry starch to your slime to make it less sticky.
