Get Rid of Excess Beer Foam by Swirling It with Your Greasy Finger

Pouring a beer properly is an art that many of us haven’t quite mastered. Mess it up and you’ll be left with a glass full of foam. You can either shrug and drink it, wait for the froth to settle—or you can take a cue from the American Chemical Society's latest Reactions video, and use science to make your brew sippable.

The ACS recommends touching a piece of pizza, French fries, or even your nose, and then swirling your greasy finger through the bubbles. The oil breaks the bonds between beer proteins and hop compounds, causing the foam to dissipate. (Pro tip: Leave a little foam, as it lends the brew extra aroma and makes it creamy.) To learn more about the chemistry of beer bubbles, watch the clip above.

How Long Could a Person Survive With an Unlimited Supply of Water, But No Food at All?

How long could a person survive if he had unlimited supply of water, but no food at all?

Richard Lee Fulgham:

I happen to know the answer because I have studied starvation, its course, and its utility in committing a painless suicide. (No, I’m not suicidal.)

A healthy human being can live approximately 45 to 65 days without food of any kind, so long as he or she keeps hydrated.

You could survive without any severe symptoms [for] about 30 to 35 days, but after that you would probably experience skin rashes, diarrhea, and of course substantial weight loss.

The body—as you must know—begins eating itself, beginning with adipose tissue (i.e. fat) and next the muscle tissue.

Google Mahatma Gandhi, who starved himself almost to death during 14 voluntary hunger strikes to bring attention to India’s independence movement.

Strangely, there is much evidence that starvation is a painless way to die. In fact, you experience a wonderful euphoria when the body realizes it is about to die. Whether this is a divine gift or merely secretions of the brain is not known.

Of course, the picture is not so pretty for all reports. Some victims of starvation have experienced extreme irritability, unbearably itchy skin rashes, unceasing diarrhea, painful swallowing, and edema.

In most cases, death comes when the organs begin to shut down after six to nine weeks. Usually the heart simply stops.

(Here is a detailed medical report of the longest known fast: 382 days.)

This Concrete Block Makes a Fine Espresso

Have you ever thought your kitchen could use more of a Soviet Union vibe? Do you find the fixtures in abandoned buildings charming? Then the AnZa espresso machine—essentially a coffee maker encased in a concrete block—may be for you.

According to Curbed, the AnZa is part of the art and installation aesthetic dubbed Brutalism, an architectural movement using spare, blocky designs. Moving away from the sleek, shiny appearance of most modern appliances, design firm Montaag crafted a rough block with simple knobs. As post-apocalyptic as it may look, it’s reputed to make a very good cup of espresso. And it’s “smart”: a smartphone app can adjust the brewing temperature to the user’s preference.

The project’s Kickstarter recently met its $145,000 goal and is now accepting preorders at Indiegogo for $799. You can hoist this subjectively beautiful appliance on your countertop beginning in March 2018.
