Cutting onions is one of the easiest ways to make yourself cry and feeding them to your pet will make them extremely ill. The same chemical compounds are responsible for both adverse reactions.

Chocolate is one of life's greatest inventions. You can eat it whole, you can use it to flavour things, you can drink it and you can melt it into a deliciously sweet paste. But one chocolate bar defies this logic and today I discovered this. Yes, we're talking about Cadbury's Flake.

'All-wheel drive' and 'four-wheel drive' are often used interchangeably. In reality, they are very different vehicles and it depends on whether power is sent to the front or rear of a vehicle. Here's a professional rally driver explaining the difference between these two ever-more confused terms.

Why do witches wear tall pointy hats? You've probably never questioned it through years of Harry Potter and Hocus Pocus, but it has to have come from somewhere, right? As it turns out, that hat's probable origin, like a lot of human history, is pretty racist.

Do you know your dog's age in 'dog years'? You know: supposedly a dog is seven dog years old on its first birthday and all that? Well, as it turns out, that figure isn't really accurate at all, and it's thrown even further out of whack when you realise that all dog breeds age at different rates. So if you want to figure out your pooch's actual age in dog years, here's how to do it.

The Melbourne Cup is sometimes deplored but the central place it holds in Australian mainstream culture is rarely disputed. And its promotion came quickly. Its first running in 1861 drew about 4000 spectators. In 1870 an estimated 30,000 attended and 100,000 was claimed for the 1880 running – about a third of the population of Melbourne. Even allowing for some boasting spurred by colonial rivalry, these are remarkable figures.

The camel spider is a type of Arachnid found in most deserts around the world (with the exception of Australia, thank God.) They are notable for having ten limbs, the biggest jaws of any Arachnid and the ability to grow to distressingly large sizes. Oh yeah, and they literally scream while chasing down prey.

What's inside the glowing briefcase in Pulp Fiction? It's one of the greatest mysteries in cinema. Writer and director Quentin Tarantino has remained deliberately coy on the subject, vowing to never reveal the answer. "It's whatever the viewer wants it to be," he once teased.

Except that's not quite true. The answer is explicitly spelled out in an original screenplay draft. (Spoiler: It has nothing to do with Marsellus Wallace's soul.)

Peter Brock was, without question, one of Australia’s best known and most successful auto racers, ever. He also ran a great factory-approved tuning company. But the story of his tragic downfall is perhaps the most fascinating of all. It involves a box of crystals that tap into mythical orgone energy. Seriously.

The modern Tesla is known for making modern electric cars, but the truth is the original Nikola Tesla made an electric car — and he did it all without batteries, way back in 1931. Or did he?

The ketogenic diet (or 'keto' for short) involves the eradication of most carbs from your diet in favour of proteins and fats. It has exploded in popularity among women in recent years, with multiple mummy blogs singing its virtues.

However, there's a slightly icky side-effect you may wish to ponder before embarking on a high-fat, low-carb diet. In short, it can cause a marked change in vaginal odour - AKA the 'Keto Crotch'.

Chronic wasting disease has now been reported in deer, elk, and moose in 24 states across the US, according to the CDC. The disease isn’t new, but its nickname is: you can now read sensational headlines about “zombie deer.”

Quick, think of things that are fast! Rockets? OK. Cheetahs? Sure, absolutely. Bullets? Oh, yes, quite. A bowl of rich, creamy soup? Ah, generally, no. Not so much. Then why do we call cars that have been made to go faster “souped-up?”

There’s an extremely common design trend that may have slipped by right under your nose, slowly taking over seemingly ever new car on the road, one by one. It’s only maybe a couple inches wide at most, and at all four corners of the car. It’s purpose a mystery, until now.

I’m not much of a cryer, but when I do, I bawl.

The English language was first spoken in early medieval England around 1400 years ago. This gradually gave rise to today's 'Modern English' which became the dominant form by the 1550s. Today I discovered some of the earliest English words that are still in common usage today.

Earlier this week, Google's CEO Sundar Pichai faced a House Judiciary Committee in the United States Congress to answer questions about recent data breaches and other important security matters. So, naturally, the discussion turned to extremely serious and important matters. Like why searches on Google for the word "idiot" turn up images of President Donald Trump.

In 1930, a wild, black-haired, green-eyed tomboy commanding her motorcycle caught the eye of a man named Tommy Wisdom. He was working as a journalist at a motorsport magazine and knew that this beautiful woman was going to be his partner in life.

Two blowflies were chowing down on a dog turd mixed with their own vomit for lunch. One of the flies burped. The other replied: "Don't be so disgusting while I'm eating!"

But anyway.
