Balancing in High Heels

This is how it works: you're young until you're not.
You love until you don't. You try until you can't.
You laugh until you cry. You cry until you laugh.
And everyone must breathe until their dying breath.


Ask me anything...no, really. Anything.

Using Non-Newtonian Fluids to Fill Potholes (news.sciencemag.org)

CLEVELAND, OHIO—So-called non-Newtonian fluids are the stars of high school science demonstrations. In one example, an ooey-gooey batter made from corn starch and water oozes like a liquid when moved slowly. But punch it, or run across a giant puddle of it, and it becomes stiff like a solid. Pour it on top of a speaker cone, and the vibrations cause the fluid to stiffen and form strange tendril-like shapes. Now, a group of college students has figured out a new use for the strange stuff: filler for potholes.

The students, undergraduates at Case Western Reserve University in Cleveland, devised the idea as part of an engineering contest sponsored by the French materials company Saint-Gobain—and took first prize last week. The objective was to use simple materials to create a novel product.

“So we were putzing around with different ideas and things we wanted to work with—and we were like, what’s a common, everyday problem all around the world that everybody hates?” explains 21-year-old team member Curtis Obert. “And we landed on potholes.” He and four other students decided on a non-Newtonian fluid as a solution because of its unusual physical properties. “When there’s no force being applied to it, it flows like a liquid does and fills in the holes,” says Obert, “but when it gets run over, it acts like a solid.”

This is incredible!

Oobleck in potholes!

    SO AWESOME. YEAH MATERIALS. I will never look at ketchup the same way again, it’s a shear-thinning fluid!
