Alex S. asks: Why doesn’t oil and water mix? Made of different elements, and with distinct structures, densities and even dissimilar polarities, it’s no wonder oil and water don’t get along. They can be forced to cooperate, however, and there are several examples of this that are likely currently sitting in your pantry or refrigerator. But why don’t oil and […]

Alex B. asks: Why are farts flammable? Contrary to popular belief, it’s probably not methane leaking from behind that reckless “bros” light on fire (known as pyroflatulence); rather, it’s most likely primarily hydrogen. In a typical, healthy body, human farts are comprised primarily of hydrogen, nitrogen, some carbon dioxide and potentially a small amount of methane and oxygen. These farts […]

First discovered back in the 1930s, chlorine trifluoride is a rather curious chemical that easily reacts, sometimes explosively, with just about every known substance on Earth. Just to get the ball rolling, here’s a few of the more unusual things chlorine trifluoride is known to set fire to on contact: glass, sand, asbestos, rust, concrete, people, pyrex, cloth, and the dreams of children… […]

K. Crain asks: Why aren’t humans furry like other primates? Although there is no definitive account of why we lost our body hair when every other primate is covered with the stuff, there are a handful of compelling theories that may explain our hairless condition.

They examined how much disgust people would feel and show after smelling a variety of odors, including armpits, garbage and farts. Among the stinks examined, farts elicited the strongest […]

Given that humans have been using lead in various product for over 8,000 years (with the first known mining of it in Anatolia around 6500 BCE), you might be surprised to learn that we have known that lead is dangerous and shouldn’t be trifled with since at least 150 BC, when […]
