This Everyday Slime Is Full of Built-In Magic Tricks

Polyethylene oxide (also known as POLYOX) doesn’t sound very fun or exciting, but in the video above, science presenter Steve Mould illustrates the magical abilities of the slime—which you probably encounter on a daily basis.

As Mould says, polyethylene oxide makes up the lubricated strips on many disposable razors. In the video, he has it dissolved in a beaker of water and explains that the polymer is made of long-chain molecules which are all connected. “So although this is a liquid,” he says, “when the liquid flows, those molecules tug on each other, meaning it behaves in a really weird way.”

That "weird way" results in a self-pouring liquid and a cool syringe trick you have to see to believe. The polymer is just one of the many topics Mould tackles in his YouTube videos, so check it out and prepare to wow your friends with tales of this seemingly otherworldly ooze when Ghostbusters comes out in July.

Tracing a word’s origin and evolution can yield fascinating historical insights—and the weird nicknames used in some states to describe their residents are no exception. In the Mental Floss video above, host John Green explains the probable etymologies of 29 monikers that describe inhabitants of certain states across the country.

Some of these nicknames, like “Hoosiers” and “Arkies” (which denote residents of Indiana and Arkansas, respectively) may have slightly offensive connotations, while others—including "Buckeyes," "Jayhawks," "Butternuts," and "Tar Heels"—evoke the military histories of Ohio, Kansas, Tennessee, and North Carolina. And a few, like “Muskrats” and “Sourdoughs,” are even inspired by early foods eaten in Delaware and Alaska. ("Goober-grabber" sounds goofier, but it at least refers to peanuts, which are a common crop in Georgia, as well as North Carolina and Arkansas.)

Learn more fascinating facts about states' nicknames for their residents by watching the video above.
