Slime is both a liquid and a solid! It is a non-Newtonian fluid, whose viscosity (which is how fast or slow a fluid flows) changes depending on pressure.
Slime’s consistency depends on the polymers. Polymers are materials made of identical repeating chains of molecules connected by covalent chemical bonds. Glue, for example, is a polymer, and it flows because these chains slide past each other freely. In slime, when glue mixes with an activator, such as borax or saline solution, the polymers are cross-linked therefore giving the slime a more solid consistency.
Why not make the winter break more festive and fun by creating some holiday slime with your family?! Here is a simple recipe for Holiday Glitter Slime!
- One bottle of glitter glue (6oz)
- 1 1/2 tablespoons of contact lens solution
