"Okay Luca, we know you're excited about your first trip to space and being chosen to lead the spacewalk, but just some basics before you go. The suits are bulky and can hamper movement a bit, you may feel slightly claustrophobic at first but that tends to pass, and it's awfully hot in there but again, pretty manageable."
"Roger. Anything else?"
"Well no not really, go ahead and strap that harness tight, we're preparing for launch. Oh by the way every now and again the helmet completely fills up with water and we don't have a fucking clue why or how to fix it see you next Thursday!"

There's an incredible irony to drowning in space.

Not just deadly. IF you survive an ectopic pregnancy you can still end up with other damage to your reproductive organs making future pregnancies difficult.

I'm pretty sure that's Jonathan Davis's solo music venture.

And politicians who don't understand this want womens options limited to the point they may have to suffer through an experience like this because 'life is sacred'.
I couldn't even imagine being in Texas and having acradiac twins with one being just a head and spinal cord, then having to argue to the law that an abortion is necessary in that case.

Exactly. Ectopic pregnancies can be deadly.

Vacuum kills pretty quick. If you try holding your breath, you'll rupture your lungs, so the best thing to do is actually exhale before exposing yourself to vacuum. You can imagine this doesn't give you very much air left to live off of. You will lose consciousness within seconds, and you won't have much longer than that before you start suffering irreparable brain damage.
EDIT: I may be wrong about this; read the replies.

If it sulks in a reef and has two sets of teeth, that's a moray

And those 40 cells differentiate into 3 subtypes prior to beginning their development. Gestation is wild

You could poke a hole and then plug it if you wanted to. If you ended up just plugging it with whatever nearest, including skin, you would end up with a hickey but nothing else.

Molar pregnancues are the grossest and saddest things. So sad

Reply to comment by j0rmungund in TIL that Barq's Root Beer was first created by Edward Barq in Biloxi, Miss, in 1897. In 1934, Barq and a former employee, who moved to New Orleans, agreed to each distribute their own version of the root beer, with the New Orleans version having a red label and the Biloxi version having a blue one. by jdward01
Is there a chart that explains those?

Boil doesn't mean hot, however, whereas evaporation causes cooling. The rapid evaporation of some of the water would cause the rest of the water to freeze.

There are many stories about prophecies being fulfilled by people trying to prevent it but are any stories where a prophecy got subverted because someone was actually trying to fulfill it?

The pressure in space is essentially zero, so water boils instantly.

Not true, you’d have explosive decompression and lose consciousness within seconds. It isn’t like holding your breath. The air is sucked out of you instantaneously.

It would flash boil. Water boils at lower and lower temperatures as pressure decreased. That's why there are different cooking instructions on the back of the box for "high altitudes". Takes longer to cook something in Denver because things boil at a lower temperature.
In space the pressure is basically zero, so water just immediately boils.
