    WTF is Up with Nuclear Fission?

    At 8:15 AM local time on August 6, 1945, the Boeing B-29 Superfortress Enola Gay of the U.S. Army Air Forces’ 509th Composite Group dropped a single bomb over the Japanese city of Hiroshima. Nicknamed Little Boy, the bomb detonated at an altitude of 580 metres or 1,900 feet, unleashing the explosive equivalent of 15,000 tons of TNT. The immediate fireball and blast wave obliterated buildings out to a radius of 1.6 kilometres or one mile, while the resulting firestorm destroyed nearly 11 square kilometres or 4.4 square miles of the city. By the end of the year, around 150,000 civilians of all ages had been killed as a result of the blast, while thousands more succumbed to injuries and radiation poisoning over the following years. The atomic bomb had made its terrifying combat debut. But while Little Boy was fuelled by 64 kilograms or 141 pounds of highly-enriched Uranium, astoundingly only 1.5% of this material or 800 grams actually participated in the nuclear reaction, while a scant 0.7 grams was converted to pure energy. That’s right: a piece of Uranium lighter than a paperclip obliterated an entire city. Such is the astounding power of nuclear fission, which is so much more efficient than any chemical reaction that a single kilogram of Uranium burned in a nuclear reactor can produce as much energy as 3,000 tons of coal. But…how? What makes nuclear fission so extraordinarily powerful? How does it all work? Well, let’s dive into the fascinating process and science that allows us to unlock the incredible amount of energy that lies within all matter.

    The Saga of the First Major Car Race

    As the official name of Paris–Bordeaux–Paris Trail suggests, the idea of this particular event was to see who could drive from Paris to Bordeaux and back again in the quickest possible time. For reference, this was a distance of 1,178 km or 732 miles on the roads of the day. So what was so special about this particular race? Well, for the first time in history, a large group of automobiles would be pitted against one another in a first to finish-style event, with said race kicking off on June 11, 1895. The brainchild of a group of automobile enthusiasts and journalists keen to promote the then fledgling French automobile industry, the race was seen as a way to both test the limits of cars at the time as well as test the commercial viability of motor racing as a spectator sport. Although, as we’ve previously noted, this was only a couple decades after an era in which competitive walking was one of the world’s most popular spectator sports, so the competition was pretty light. And, to be perfectly clear- we’re not talking speed walking- just regular leisurely walking for hours and hours on end… In fact, certain walking matches were known to draw tens of thousands of spectators. Yes, before YouTube, our forebears found watching people casually walking in circles for sometimes days on end without stopping great entertainment, though to be fair this was...

    The Extremely Weird, Drug-Filled, Forgotten History of 7UP

    Food in the past could be horrifying. Prior to the introduction of regulations like the United States Pure Food and Drug Act of 1906, it was disturbingly common for manufacturers to add all sorts of inedible or even genuinely toxic substances to food to make it last longer, make it look more appetizing, or cut down on expensive ingredients and maximize profits. Boric acid and formaldehyde in milk. Brick dust in cinnamon. Bone meal or plaster of Paris in flour and bread. Lead-based dyes in jelly and jam. At one point, S.E. Massengill Company even added diethylene glycol to a common medicine to help make it taste sweeter and more easy to consume… For the uninitiated, diethylene glycol, commonly used today in antifreeze and as a solvent, is highly poisonous, and was known to be so at the time as well. Yet the substance was nonetheless added to the medicine targeted at children anyway, with about 100 deaths resulting before they recalled the medicine. Although noteworthy even with the recall, didn’t bother to tell the doctors prescribing it that there was any urgency in that, nor the danger their existing stocks of the medicine posed if they didn’t return them, and instead, continued to sell it. The owner of the company, Dr. Samuel Evans Massengill, responded to the outrage over the deaths by simply stating, “My chemists and I deeply regret the fatal results, but there was no error in the manufacture of the product. We have been supplying a legitimate professional demand… I do not feel that there was any responsibility on our part.” Much more on this story and how it finally got the government to step in and start regulating consumable products later in the Bonus Facts, and how this all led to Kinder Surprise Eggs being illegal in the United States. Which, yes, they still are. Watch to the end before commenting I’m wrong, and you’ll save yourself having to edit your comment. But for now, other questionable substances were part of the appeal of the product itself - most infamously the cocaine in Coca-Cola. Paired with caffeine from the Kola nut, this ingredient was originally chosen by the drink’s inventor, pharmacist John Pemberton, as a treatment for morphine addiction and a stimulating alternative to alcohol. Cocaine was not fully eliminated from the official formula until 1929, though the Coca-Cola company continues to use processed coca leaves in the drink’s manufacture, being the largest consumer of that plant outside of the illegal drug trade. But while it is the most famous example, Coca-Cola was not the only classic soft drink to contain psychoactive drugs, with another iconic brew originally including a mood-altering medication still taken by millions of people to this day. This is the weird forgotten history of 7UP.
