Where Did the Looney Tunes “Acme Corporation” Come From?

Reader Brian wants to know: Why is Acme the stock company name used in cartoons and other pop culture?

The Acme Corporation is a mysterious conglomerate that appears to make every product imaginable—from rocket-powered roller skates to dehydrated boulders—across several fictional universes. It’s a ubiquitous go-to name for cartoons (thanks largely to its repeated use in the Road Runner and Wile E. Coyote segments on Looney Tunes and Merrie Melodies), but also the name of plenty of reputable, real-world businesses.

Acme isn’t a made-up word or a jokey acronym, but comes the Greek akme (the "highest point” or “peak,” and often used to mean the best of a category). Its heavy use in cartoons comes from its popularity as a name in the era when the Yellow Pages and other alphabetized phone directories became common.

We’ll turn it over to Chuck Jones, who worked as an animator, writer and director on Looney Tunes and Merrie Melodies cartoons for some 30 years, to explain it a little more. He said in interviews for the 2009 short documentary, Chuck Jones: Memories of Childhood:

“Since we had to search out our own entertainment, we devised our own fairy stories. If you wanted a bow and arrow, you got a stick. If you wanted to conduct an orchestra, you got a stick. If you wanted a duel, you used a stick. You couldn't go and buy one. That’s where the term acme came from. Whenever we played a game where we had a grocery store or something, we called it the ACME corporation. Why? Because in the yellow pages if you looked, say, under drugstores, you'd find the first one would be Acme Drugs. Why? Because “ac” was about as high as you could go. It means the best, the superlative.”

Why Does Hand Sanitizer Have an Expiration Date?

The coronavirus pandemic has turned hand sanitizer from something that was once idly tossed into cars and drawers into a bit of a national obsession. Shortages persist, and people are trying to make their own, often to little avail. (DIY sanitizer may not be sterile or contain the proper concentration of ingredients.)

If you do manage to get your hands on a bottle of Purell or other name-brand sanitizer, you may notice it typically has an expiration date. Can it really go “bad” and be rendered less effective?

The short answer: yes. Hand sanitizer is typically made up of at least 60 percent alcohol, which is enough to provide germicidal benefit when applied to your hands. According to Insider, that crucial percentage of alcohol can be affected over time once it begins to evaporate after the bottle has been opened. As the volume is reduced, so is the effectiveness of the solution.

Though there’s no hard rule on how long it takes a bottle of sanitizer to lose alcohol content, manufacturers usually set the expiration date three years from the time of production. (Because the product is regulated by the Food and Drug Administration, it has to have an expiration date.)

Let's assume you’ve found a bottle of old and forgotten sanitizer in your house somewhere. It expired in 2018. Should you still use it? It’s not ideal, but if you have no other options, even a reduced amount of alcohol will still have some germ-fighting effectiveness. If it’s never been opened, you’re in better shape, as more of the alcohol will have remained.

Remember that sanitizer of any potency is best left to times when soap and water isn’t available. Consider it a bridge until you’re able to get your hands under a faucet. There’s no substitution for a good scrub.

Why Are Sloths So Slow?

When it comes to physical activity, few animals have as maligned a reputation as the sloth. The six sloth species, which call Brazil and Panama home, move with no urgency, having seemingly adapted to an existence that allows for a life lived in slow motion. But what makes sloths so sedate? And what horrible, poop-related price must they pay in order to maintain life in the slow lane?

According to HowStuffWorks, the sloth’s limited movements are primarily the result of their diet. Residing mainly in the canopy vines of Central and South American forests, sloths dine out on leaves, fruits, and buds. With virtually no fat or protein, sloths conserve energy by taking a leisurely approach to life. On average, a sloth will climb or travel roughly 125 feet per day. On land, it takes them roughly one minute to move just one foot.

A sloth’s digestive system matches their locomotion. After munching leaves using their lips—they have no incisors—it can take up to a month for their meals to be fully digested. And a sloth's metabolic rate is 40 to 45 percent slower than most mammals' to help compensate for their low caloric intake. With so little fuel to burn, a sloth makes the most of it.

Deliberate movement shouldn’t be confused for weakness, however. Sloths can hang from branches for hours, showing off some impressive stamina. And because they spend most of their time high up in trees, they have no need for rapid movement to evade predators.

There is, however, one major downside to the sloth's leisurely lifestyle. Owing to their meager diet, they typically only have to poop once per week. Like going in a public bathroom, this can be a stressful event, as it means going to the ground and risking detection by predators—which puts their lives on the line. Worse, that slow bowel motility means they’re trying to push out nearly one-third of their body weight in feces at a time. It's something to consider the next time you feel envious of their chill lifestyle.
