How Much Paint Would it Take to "Cover the Earth"?

If you’ve done any painting lately, you’ve probably encountered the Sherwin Williams logo:

Sherwin Williams - "Cover the Earth"

The visual of a can of paint larger than the moon being poured over Earth has always been something of a curiosity to me. Setting aside the obvious environmental concerns (to put it lightly) of literally covering the planet in paint, I can’t help but wonder when I see that image: How much paint would it really take to “Cover the Earth”?

A similar question was tackled by the venerable Randall Munroe in a February entry of his “What If?” series, but the question he was addressing was slightly different (“Has humanity produced enough paint to cover the entire land area of the Earth?”). I want to know how much paint it would take to literally pour out a can and have it completely cover the planet—land, water, and all.

Let’s figure out just how big that giant planet-destroying Sherwin Williams paint can would really need to be in order to “Cover the Earth” with one coat of paint.

We’ll start with the surface area of Earth, which comes in at 196.9 million square miles.

Surface Area of Earth

Although the logo shows the planet-painting in progress rather than complete, we’re going to assume given the amount of coverage shown, the large splash at the top, and the fact that the can is tipped almost completely over that there was enough paint in the can to cover the entire planet once over with a standard coat of exterior paint.

For this project we’ve selected Sherwin Williams Resilience™ Exterior Acrylic Latex Paint. Here’s the product description:

Don’t let weather worries ruin your painting schedule. Resilience® Exterior Acrylic Latex paint gives painted exteriors exceptional moisture resistance so you don’t have to postpone painting when the forecast calls for rain, or quit working early in the day because you’re concerned about dew. You can apply Resilience in temperatures as low as 35°F.

Sounds perfect. Plus, the base color is Red, just like the logo. According to the technical data sheet, Resilience paint covers 350 to 400 square feet per gallon. We’ll go with the midpoint of that range and assume that a gallon of paint covers 375 square feet of Earth on average.

Now it’s time for a bit of math. One mile is 5,280 square feet, so a square mile is 5,280 feet * 5,280 feet = 27,878,400 square feet. Multiply the 196.9 million square mile surface area of Earth by 27.9 million and we get 5.5 quadrillion square feet. Divide that by our 375 square feet per gallon coverage and we come to 14.6 trillion gallons of paint to cover the planet in one coat of Sherwin Williams Resilience™ Exterior Acrylic Latex Paint.

So how big would that giant SWP paint can need to be in order to hold 14.6 trillion gallons? A standard 1-gallon paint can measures 6⅝” diameter by 7½” height, occupying total volume of 1.12 gallons. If we assume that our mega-can would be the same shape, just scaled up, we’ll end up with a can of paint that has a diameter of 2.6 miles and is 5.8 miles tall.

Here’s a visualization of our Earth-covering can of paint in comparison to some recognizable landmarks:

"Cover the Earth" Paint Can Visualization

That’s a pretty big paint can, but it’s actually a lot smaller than the moon, which has a diameter of 2,159 miles. Note the surface of the moon in the visualization, to give you a sense of scale.

Sherwin Williams Moon-Sized Paint Can

So, what if we actually had a can of paint with as much volume as the moon, as shown in the logo?

It turns out a can that large would hold enough paint to “Cover the Earth” with over 2,800 coats of paint. After you poured a moon-sized can of paint over Earth, the entire planet would be covered in about a foot of Sherwin Williams Resilience™ Exterior Acrylic Latex Paint.

I’m no painting expert, but I think that would be going a little overboard.

Which is More Dangerous: Climbing Rainier or the “Deadliest Job”?

With the news a few weeks ago of the death of six climbers on Mount Rainier, I found myself wondering… just how dangerous is climbing Rainier, anyway? Is it really more dangerous than other risky activities that we do every day?

For example, thirty thousand people in the United States die every year in automobile accidents, but since we don’t see front page headlines about every single fatal collision, perhaps we just perceive the risk to be lower than climbing a mountain. Maybe mountain climbing is just as dangerous as your daily commute, but your perception is skewed.

In order to answer my question, I collected fatality rate data on a variety of activities to compare with climbing Rainier. Here are the risky activity contestants, and the average annual number of fatalities that occurred during each over the last ten years or so.

  • walking: ~4,000 fatalities
  • bicycling: ~600 fatalities
  • driving a car: ~30,000 fatalities
  • driving a motorcycle: ~4,000 fatalities
  • commercial flight: ~14 fatalities
  • skydiving: ~22 fatalities
  • Dungeness crab fishing: ~3 fatalities
  • climbing Mount Rainier: ~1 fatality

I wanted to include a good variety of activities, from things we all do every day like walking, riding a bicycle, or driving, to things that most of us probably don’t do, but are widely considered to be dangerous, like skydiving and professional Dungeness crab fishing, an activity that is widely regarded as the “deadliest” occupation in the country.

To compare everything on a relatively level playing field, I divided the total number of deaths over the last ten-ish years in each activity by the total number of trips taken in that activity in the same period, then multiplied by 100 million to bring all the numbers up to a scale that’s easier to visually compare.

Here’s the result:

Fatality Rate of Various Activities (deaths per 100 million trips)

Okay then! As it turns out, mountain climbing is ridiculously more dangerous than every other activity I was able to find data on. It’s not even remotely in the same league. Climbing Mount Rainier is 14 times more deadly than the “deadliest job” of fishing for crab in Alaska.

Now, it’s worth noting that normalizing for deaths per 100 million trips isn’t totally fair, since most people who attempt to summit Rainier will probably only do it once or twice in their lives, while the average person probably takes 50 to 100 thousand trips in a car through the course of their lifetime. Your odds of dying in a car wreck on any given trip are fairly low, but the odds that you might die in a car wreck sometime in your lifetime are much higher.

To quantify that, the odds that you’ll die in an attempt to summit Rainier are roughly 0.02 percent. The odds that you’ll die on any given trip in your car is 0.0000038 percent. But the odds that you’ll die in a car wreck sometime in your life is roughly between 0.19 percent and 0.38 percent—considerably higher than your odds of dying in a single attempt to summit Rainier. In other words, your chances of dying from driving at some point in your life are about 19 times greater than your chances of dying while climbing Rainier.

Still, I was surprised that climbing Rainier is that dangerous per trip. A 0.02 percent fatality rate sounds low, but it’s way, way higher than every other activity on the list. Of course, it’s not even remotely the most dangerous thing you can do. If I had included a bar for climbing Mount Everest, it would have made everything else on the chart look minuscule. Everest has around a one percent fatality rate—1,000,000 deaths per 100 million trips compared to “just” 15,942 for Rainier. And according to Mental Floss, there are at least five mountains even more dangerous than Everest—including Annapurna in Central Nepal, with a 22 percent death rate (22,000,000 deaths per 100 million trips).

So basically I won’t be climbing any mountains. Ever.

Gordon Sands Threatens Seattle Bubble with Google Disavow in Misguided Attempt to Clean Up BankruptcyAction.com Comment Spam

Last week I got an email from Gordon Sands, “a principal” of BankruptcyAction.com—a website I’d never heard of—claiming that Seattle Bubble contains “link(s) to BankruptcyAction.com.” The claimed reason for this random email was to remove a link on my site “because the links are not in the same niche as our site,” but the real reason was obviously that the proprietors of this site had previously engaged in link-spamming, were punished by Google, and are now scrambling to get publishers to remove their comment spam links (via BoingBoing).

bankruptcyaction-threats_01

I especially enjoyed the big, red, bold text at the end of the email threatening to use Google’s Disavow tool as some sort of weapon against me should I not comply with his demand. Despite the vague claim in the email (no specific link to the post or posts in question) and the unnecessary threat, I decided to look into it, because to my knowledge no spam comments have ever gotten through on my site thanks to Akismet.

As best I can tell, there exists a grand total of one link to BankruptcyAction.com on Seattle Bubble. It was placed by a long-time reader in a 2008 comment. Since I’m not in the habit of editing reader comments unless the person who posted the comment requests it or it violates my comment policy, I politely declined to modify or delete the link in my reply:

bankruptcyaction-threats_02

This did not please Gordon, who indicated that he intended to follow through with his big scary threat:

bankruptcyaction-threats_03

Since Gordon seemed to be operating under some sort of false assumption that I care whether or not BankruptcyAction.com disavows my site to Google, I thought I would clear things up for him.

bankruptcyaction-threats_04

In reply: more veiled threats from Gordon.

bankruptcyaction-threats_05

I thought it only fair that I give Gordon a few tips, like if you want someone to do something for you maybe don’t lead off with giant bold threats.

bankruptcyaction-threats_06

Gordon’s final word on the matter confirmed my original suspicion: he’s trying to undo the damage done by comment spam.

bankruptcyaction-threats_07

That the comment in question on Seattle Bubble is obviously not spam is of no concern to Gordon Sands or BankruptcyAction.com. And because apparently he felt like his threats did not go far enough, he decided to close our conversation by calling me “a sensitive woman,” which I assume was meant to be an insult. But I am the one who “can’t handle your business.” Right.

Good luck to you as well, Gordon Sands and BankruptcyAction.com! You’re going to need it.

[Update]
Oops, I guess Gordon Sands decided he wasn’t done “wasting time” after all!

Keep digging, Gordon.

Don Adams, 86 in Get Smart & Inspector Gadget

I got the recently (finally) released “Inspector Gadget Megaset” for Christmas, and I noticed a familiar number on the box…

Don-Adams-86

Don Adams’ “Get Smart” character Maxwell Smart was Agent 86.

Don Adams’ voiced the goofy 1980s cartoon character Inspector Gadget in a total of 86 episodes.

I just thought that was an amusing and random coincidence.

Also, I love Don Adams. He was great.
