Have you ever thought what would happen if everyone in the world (all 7.5 billion of us!) sneezed at the exact same time? Worst case scenario, there may be some accidents on the road. After all, your eyes automatically close whenever you sneeze. Well, this worldwide “Achoo” would be pretty loud too, especially for those who happen to be at a stadium.

Speaking of stadiums, you’d likely see a cloud form since one sneeze can contain up to 40,000 droplets of mucus! And all those germs, ick! Or if you’re watching TV when it happens. The news anchor would be stopped mid-sentence. This event would go down in history! People will ask each other, “Where were you on the day the whole world sneezed?”

Cell phones certainly make our lives easier, but they can also be dangerous. Sometimes phones explode! Literally. This usually happens with a lithium-ion battery, which most modern gadgets are equipped with.

How often do you take elevator selfies? After all, that’s what the mirrors inside them are for, right? Or could it be for safety and monitoring reasons? Or maybe they are hiding some secret parts of the elevator you aren’t supposed to see?

Back in the 1920’s when modern-type elevators were becoming more and more popular, a lot of people were anxious about going for a ride. Hotels, stores, and office buildings came up with a solution – they started playing calming music inside. So maybe the mirrors are there for the same purpose?

Believe it or not, but you have to thank mosquitoes for the invention of air conditioning, or, at least, its forefather! No one loves them in the 21st century, but back in the 19th, those guys were a real nightmare. Things were especially bad in swampy areas of Florida.

A local physician and inventor Dr. John Gorrie was trying to find a way to drain the swamps, and while he was at it, he got this revolutionary idea in 1841. He realized the problem was literally in the air. So cooling the air could fix it!

Are modern humans the pinnacle of the food chain, the strongest and most intelligent creatures ever to walk this Earth? Maybe now, but once upon a time, we had some real competition: Neanderthals.

Wait, like, cave people? Weren’t Neanderthals our ancestors? Nope! We came from the Cro-Magnon, which were early modern humans. Neanderthals were a separate branch of humans. Their DNA is even different from ours, so we can safely say that Neanderthals were a completely different species.

The first and most important thing any experienced weatherman, survivalist or tornado chaser will tell you is you need to know what you’re dealing with.

When the battery runs out, it’s nerve-racking, but unfortunately, it happens. The more functions our devices provide, the more power they need, and they’re hungrier than hungry hippos at this point! That’s why charging technology is all the rage now, and the new big thing is wireless charging.

Even though we’re just now seeing this technology take off, the basics of how it works were discovered not long after we started to understand what electricity is. Near the end of the 19th century, engineering mastermind Nikola Tesla showed that two powerful magnetic fields can slightly transfer energy between their sources when they interfere with each other. This trick found its use more than a hundred years later!
