What is sticky water?

Sticky water is a term that refers to a non-Newtonian fluid that exhibits both liquid and solid properties. Unlike regular water, sticky water becomes more viscous and resistant to flow when it is subjected to certain forces or stresses. This unique characteristic creates a "sticky" or "gooey" effect, making it difficult to pour or move like traditional liquids.

While the term "sticky water" may be used figuratively in some contexts, there are actual substances that exhibit this behavior. For example:

1. Ooblek: Ooblek is a well-known example that can be made by mixing cornstarch and water. When gently stirred or pressed, it acts like a liquid and flows easily. However, when a sudden force is applied, it temporarily behaves like a solid, becoming firm and difficult to move. This property is the result of a process known as shear thickening.

2. Slime: Slime is another popular sticky water substance often made using various combinations of glue, water, and other ingredients like baking soda or borax powder. It has a thick, gooey consistency and demonstrates non-Newtonian behavior. When left undisturbed, it flows like a liquid, but when stretched or pressed, it stiffens and becomes resistant to deformation.

3. Honey: Although not commonly referred to as sticky water, honey exhibits similar characteristics. It is a viscous liquid composed primarily of sugars and water. While honey flows freely under normal conditions, it can become sticky and stringy when poured or drizzled due to its high viscosity and slow molecular movement.

4. Gels: Some gels, like those found in jelly or certain personal care products, can behave like sticky water. They are composed of a network of interconnected molecules that trap water and other components. Under normal conditions, they are soft and pliable, but when subjected to external forces, they can temporarily solidify or thicken.

The phenomenon of sticky water can be fascinating and entertaining, and it demonstrates the interesting properties of non-Newtonian fluids that challenge our everyday understanding of how liquids and solids behave. These substances find applications in various fields, including research, education, and the creation of novel materials with unique properties.
