Constarch QuickSand (Oobleck)

ACES Activity of this week: Made quicksand by mixing cornstarch, water and little food coloring to make it fun! It was messy fun but nevertheless lot of fun. Hard force made it behave like a solid and gentle force makes it behave like fluid.

The gooey substance formed a ball when pressed together but quickly melted when let go!

We discussed Viscosity, Newtonian fluids, Non-newtonian fluids, different types of Non-newtonian fluids (Dilatant & Psuedoplastic). Watched youtube videos that further explained what happens at a molecular level when force is applied on non-newtonian fluids.

Deliberated why understanding non-newtonian fluids is important and considered applications of non-newtonian fluids.
