We started with white school glue! Glue contains millions of long strands of molecules that are linked together like a chain. We began by mixing some water to make the glue "thinner".
Measuring out the right amount of borax solution to add to our glue, food coloring, and water mixture.
Getting ready to see the chemical reaction!
Vigorously mixing...
When you add borax to the glue, things begin to happen! The borax links the long strands of glue together! This process creates a net-like structure, making Gak behave like a solid! The "net-like" structure traps the water inbetween the strands. With this, Gak behaves like a liquid!
Gak acts like both a solid and a liquid!!! Gak is called a "Non-Newtonian fluid". It is Non-Newtonian because it does not behave the way Newton said fluids should. Who knew science could be so fun! I loved seeing the kids making observations and really getting into this activity!
It's rubbery!
It's melting!
It acts as both the solid and liquid!
Each child took home some of their creation!
Science is FUN!
