In this post we will try to demonstrate how to make quicksand in an easy way on a harmless scale. The resulting product of this project will yield us a demonstration of quicksand that will be appreciated by friends and teachers alike.

Things you will need:

• Spoon
• Water â€“ Half Cup
• Corn flour â€“ Around 1 cup
• Plastic Container â€“ Large

How to do it:

• The water and corn flour should be mixed perfectly to a thick consistency. The container should be used for the mixing and storage of the mixture.
• When demonstrating to your friends and teachers stir the mixture slowly and drip it down the spoon to show the liquid consistency of quicksand.
• When one stirs the mixture fast, it solidifies as it is a non- Newtonian fluid. Same happens when any type of force is applied on the liquid.
• Take the mixture and try to roll it into a ball. You will notice that till you apply a pressure on the substance it retains its shape and as soon as youâ€™ll stop that its consistency will revert back to liquid.

What happens?

The absorption and dissipation of energy takes place in an easier manner in Non- Newtonian fluids. This property can be proved by stuffing an uncooked egg in a packet filled with corn flour. Be sure that the egg is surrounded by the mixture and then drop it from a height. A Newtonian fluid, for instance, water would not protect the egg whereas a Non- Newtonian fluid under impact solidifies and thus protects the egg. Be extremely careful when dealing with corn flour mixture as it is very messy and solidifies easily. The rigidity in a Non- Newtonian liquid occurs as the molecules of corn flour are mixed up and canâ€™t slide over each other.
