The video is not promoting violence nor is it portraying some type of juvenile prank, but rather it is discussing some serious science. On the underside of the shovel is a flattened glob of bright orange goo that looks like Silly Putty.

Its primary goal is to provide impact protection. An avid snowboarder, he was looking for a way to protect himself from the many bumps and bruises he suffered from frequent wipeouts on his board. What makes these materials so different from regular fluids, and why are they used in so many everyday products?

In addition to his many other discoveries, Isaac Newton did some groundbreaking work with fluids. He discovered that the viscosity of most fluids is affected only by temperature. A fluid with high viscosity resists motion while a fluid with low viscosity flows easily. More viscous substances, such as syrup and honey, take longer to pour than less viscous substances, such as water.

Be careful not to confuse viscosity with density. While cream may be thicker than milk, it is actually less dense, as cream will float on top of milk. Newton observed that if a substance is heated, it will become less viscous, and if cooled more viscous. When attempting to start your car on a sub-zero morning, you may notice that the engine has a difficult time turning over, as the oil in the car is thick and sluggish. Once the engine heats up, the oil becomes less viscous and flows more easily.

Most common fluids, such as water and oil, are Newtonian. Their viscosity remains constant no matter how fast they are forced to flow through a pipe or channel. So the only factor affecting their viscosity is temperature. But the viscosity of some fluids is affected by factors other than temperature.

These fluids are termed non-Newtonian fluids. The viscosity of a non-Newtonian fluid will change due to agitation or pressure—technically known as shear stress. A shear stress will not affect the viscosity of a Newtonian fluid. Non-Newtonian fluids are polymers.

A polymer is composed of long chains of repeated units known as monomers that are strung together to yield giant macromolecules. The most common synthetic polymers are plastic, rubber, and fabrics, such as polyester and Spandex. Consider ketchup. You may need to tap the bottom of the bottle or shake it loose to get it to come out.

In doing so, you are applying a shear stress to the ketchup, causing it to become less viscous. Fluids that become less viscous when shaken or stirred are known as shear-thinning fluids.

Other shear-thinning fluids are shaving cream, toothpaste and paint. July 10, at pm. Water soluble could it be used as a thin chair seat covering perhaps with removable washable over. July 5, at am.
