Well, I guess you could say Lake Poopo is a poopoor thing now.

Reply to comment by blind_bambi in TIL that the 'funny bone' is not actually a bone in the arm, but a nerve. The ulnar nerve is connected from shoulder to hand and is protected by bones and muscles. As it passes thru the elbow it is only protected by the cubital tunnel, making it the most prone area in the body to 'strike a nerve'. by deddPan
You can easily flick it intentionally as well. Not as intense of a feeling but weird as hell.

You remember correctly! Here's an article on it.

>I am pretty sure the article gets this wrong.
It seems pretty accurate to me
>It is not that there were several liters of water (which would drown anyone immediately).
It filled slowly, and was concentrated around the back of his head. As it was in zero G it wouldn't behave like one might instinctively assume.
>It is that without adequate absorptive material (headband, chinblock) and proper ventilation, the moisture from exhalation just sheets over all internal surface in microgravity.
The visors even have anti-fogging surface coating (earlier suspected of being the reason the water tasted weird) - they're pretty impressive. The amount of moisture exhaled wouldn't account for the water present in the incident.
He definitely was in danger of drowning due to the litres of water sloshing about in his helmet. Luckily he kept calm (being a test pilot astronaut will probably help with that), as he couldn't even talk towards the end, and had to rely on hand squeezing to communicate. That's about as close to game over as you can get!

Reply to TIL a US congressman once wielded an 18-inch club made from a walrus penis bone in a congressional hearing. by gregmck
I think this was recent and also this dudes messed up. Wasn't he just in the news showing off his dick stuff in his congressional office. I'd really try to effort this one myself, but bad timing

Those names lol.
Poopo will be self explanatory for English speakers,but Titicaca sounds like "boob" and "shit", respectively, in Spanish.

Do aircraft carriers usually fire shots?

Given the cost of dental (since dental is typically not or conditionally covered as part of universal health care for some reason), that's a pretty good blessing.

After the train became stalled in a tunnel, the passengers and crew succumbed to carbon monoxide poisoning when the locomotives attempted to continue and filled the tunnel with smoke. by MorsOmnibusCommunis
You hear “500 die in Train Disaster” and you expect something more gruesome.

They’re called “Oosik” & back when I worked at a tourist trap store in Alaska we sold cribbage boards made from them. Also a poem titled “Ode to an Oosik” that was basically about how walrus “ladies” were always happy because walrus males were always hard.

​
Shoe size in the United Kingdom, Ireland, India, Pakistan and South Africa is based on the length of the last [a last is a foot-shaped template] used to make the shoes, measured in barleycorns (1⁄3 inch) starting from the smallest size deemed practical, which is called size zero. It is not formally standardised.
Note that the last is typically longer than the foot heel to toe length by 1⁄2 to 2⁄3 in or 1+1⁄2 to 2 barleycorns, so to determine the shoe size based on actual foot length one must add 2 barleycorns.
A child's size zero is equivalent to 4 inches (a hand = 12 barleycorns = 10.16 cm), and the sizes go up to size 13+1⁄2 (measuring 25+1⁄2 barleycorns, or 8+1⁄2 inches (21.59 cm)). Thus, the calculation for a children's shoe size in the UK is:child shoe size (barleycorns) = 3 × last length (in) − 12equivalent to:child shoe size (barleycorns) ≈ 3 × foot length (in) − 10.
An adult size one is then the next size up (26 barleycorns, or 8+2⁄3 in (22.01 cm)) and each size up continues the progression in barleycorns.[5] The calculation for an adult shoe size in the UK is thus:adult shoe size (barleycorns) = 3 × last length (in) − 25equivalent to:adult shoe size (barleycorns) ≈ 3 × foot length (in) − 23.
Although this sizing standard is nominally for both men and women, some manufacturers use different numbering for women's UK sizing.In Australia and New Zealand, the UK system is followed for men and children's footwear [Essentially the UK system, but they count the UK size zeros as the US size 1 and go from there]. Women's footwear follows the US sizings.
In Mexico, shoes are sized either according to the foot length they are intended to fit, in cm, or alternatively to another variation of the barleycorn system, with sizes calculated approximately as:adult shoe size (barleycorns) = 3 × last length (in) − 25+1⁄2equivalent to:adult shoe size (barleycorns) ≈ 3 × foot length (in) − 23+1⁄2.

It’s usually pretty dire if your aircraft carrier is firing shots
