You already know not to put tin foil and metal forks in the microwave, but what about grapes? In 2011, a physicist at the University of Sydney went viral after he placed a grape in the microwave and filmed the fiery aftermath.

But oddly enough, scientists couldn’t explain the phenomenon until fairly recently. A March 2019 study published in Proceedings of the National Academy of Sciences reported that the fruity fireball occurs as a result of the loose electrons and ions that cluster to form plasma when grapes get hot.

Earth doesn’t feel so enormous once you learn that the sun alone makes up somewhere between 99.8 and 99.9 percent of all the mass in the entire solar system, according to the experts at University of California, San Diego. The rest is split between the planets and their satellites, as well as the comets, asteroids, dust, and gas. What’s more, it would take one million copies of our home planet to fill up the space inside of the sun, according to Cornell University.

Planes burn a lot of fuel transporting passengers around the world, which is why Qantas airlines, one of the largest carriers in Australia, has been looking for eco-friendly alternatives. One option? A blended fuel that is half conventional fuel and half cooking oil. The end result produces around 60 percent fewer carbon emissions than traditional options.

Qantas chief executive Alan Joyce told ABC, “We need to get ready for a future that is not based on traditional jet fuel or, frankly, we don’t have a future.”

Can you imagine how little you would get done if there was bubble wrap covering your walls? Engineer Al Fielding and Swiss inventor Marc Chavannes probably didn’t consider that when, in 1957, they invented bubble wrap while trying to create a textured wallpaper by sealing two shower curtains together to trap air bubbles. Fortunately, the partners soon realized that their invention was much better suited as a packing material.

Bed bugs are near impossible to get rid of and can spread faster than watercooler gossip. But that might also be why they’ve managed to stick around for so long. Scientists believe that the bugs have existed since the time of the dinosaurs, coming onto the scene about 115 million years ago, according to a 2019 study in Current Biology.

“To think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth side by side with dinosaurs was a revelation,” said researcher Mike Siva-Jothy. “It shows that the evolutionary history of bed bugs is far more complex than we previously thought.”

Despite the many differences between humans and other creatures, there are also plenty of similarities. Many other animals have hair, a heart, eyes, and a powerful brain just like ours. But one thing we don’t share is our chins.

“If you’re looking across all of the hominids, which is the family tree after the split with chimpanzees, there [are] not really that many traits that we can point to that we can say are exclusively human,” James Pampush, co-author of The Enduring Puzzle Of The Human Chin, told NPR. “The one thing that really sticks out is the chin.”

“There’s constant daylight, and we act accordingly,” said resident Kjell Ove Hveding in a statement. “In the middle of the night, which city folk might call ‘2 a.m.,’ you can spot children playing soccer, people painting their houses or mowing their lawns, and teens going for a swim.”

The residents went so far as to host a town hall about the proposed change in June 2019, although some critics ask how a lack of time would change what these folks already do.

In other words, it’s bug poop.
