When the great pyramids were being built there was still woolly mammoths walking the earth.
There are more atoms of hydrogen in a molecule of water than there are stars in the whole solar system.
So, more than the 1 star in our solar system? Did you type that right?
Correct. I essentially said 2 is bigger than 1.
Ha! Good one, I only caught half of that joke.
You can double an hourly rate to approximate the annual wage. $30/hr ~= $60k / year.
Because 50 paid weeks * 40 paid hours = 2000 hours -> 2k
$30 * 2k = $60k
Sure, for people who work 40 hours a week, 50 weeks a year. Ugh that sounds exhausting.

I apologize if you interpreted my comment in a way that upset you or hurt your feelings. Was not my intention.
There is no thru line from mouth to urethra. You drink water, it gets absorbed into your blood, your urinary system filters excess water and waste, you pee it out. Your pee is filtered blood, the only thru line for water to take from your mouth is your ass. I understood that when it was taught, but I didn’t really think about it…
Piss comes from blood!
So does breast milk
Wow, of course you are correct, I never even thought about that.
Does the blood god accept pee? Your move, “science”!
Tell that to my body. Fluid goes in, fluid comes out. Explain that.
Everyone knows you jump in the pool in summer, smell the chlorine, and know the water is clean, right?
Fun fact- chlorine dissolved in pool water at the usual sanitation levels has almost no perceptible smell or taste.
HOWEVER, when chlorine binds with certain organic substances, especially ammonia (from the urea in sweat and urine), the result is chloramine which has a significant chlorine-y smell. Chloramine has essentially no disinfecting properties.So when you go to the public pool and get a whiff of chlorine and think ‘man they’re using a lot of chlorine today’, no, it probably means someone peed in the pool.
You’re welcome :)
Ok, but why then when you open a bottle of bleach or container of chlorine pellets, does it smell like chlorine. Do they add the piss ahead of time?
take all but 1.5mL out of that gallon jug of household bleach, then fill it back up with water. that’s roughly the concentration of chlorine in a swimming pool.
That’s pure chlorine, much higher concentration. At the concentrations of pool chlorination there’s essentially no smell.
But couldn’t they just be over-coordinating. That’s what it feels like.
Either way, I’m glad they came up with salt water systems. Much nicer.
Fun fact, salt water systems require a gadget called a salt cell which converts some of the salt in the water into chlorine. The salt isn’t actually sanitizing the water, it’s not there in nearly enough concentration to do that. Rather, the salt cell is splitting the sodium chloride into sodium and chlorine, the chlorine is then sanitizing the pool.
Overchlorination doesn’t lead to the smell, but it can dry out your skin.
Where I live, free chlorine concentrations up to 10.0 ppm are legal, but pools are normally set closer to 2.5 or 3 ppm. Even at 10, you can’t smell a chlorine smell, but my skin won’t feel great after.
However, chloramine concentrations as low as 0.2 ppm can give a chlorine smell.
One of the ways to get rid of chloramines is adding a lot more free chlorine, enough to break down the chloramines.
Try swimming in bleach and see how it compares
Ketchup, or catsup, which is the same word latinized differently, was a fish sauce from China.
The western Europeans and American colonists used the recipe, and expanded it to things like mushrooms and many other ingredients. (for proof, look at the ketchup entry on wikipedia).
Tomato ketchup (which is specified on your bottle still today) wasn’t invented until we realized that tomatoes weren’t poisonous despite their color, and their sweetness and tang totally rocked with the ketchup recipe.
Now we use it to eat frenched fries, which aren’t French! In fact, they are Belgian, and are named because they used a cooking technique invented by the French called “frenching” which has evolved into deep frying.
So, you are dipping your belgian potatoes into a chinese sauce that use a North American fruit as a base.
And with this information, you shall father nations!
And in the Philipines, ketchup refers to a banana ketchup, not a tomato ketchup.
That picture of mushroom ketchup is vile.
I bet that would be bomb on roast beef tho
Thank you. This sounds like the kind of useless knowledge I can use.
It also took a long time for tomato ketchup sales to take off because it was very difficult to make shelf stable for transporting and selling in stores. Heinz was the first company to make one that sold well. Before that, tomato ketchup was typically made at home if you wanted something vaguely decent.
The continents move at roughly the same speed that your fingernails grow.
That’s fast! They must take their supplements!
Humans can’t feel wet, what we’re actually feeling is cold. It’s why when you have a cold patch on a blanket or carpet you can’t quite figure out if it’s wet or not.
It’s actually an even greater level of abstraction: we feel the rate of heat flow through our skin. This is (kind-of) why plastic feels warmer than metal. Colder things don’t feel colder because they are colder. Colder things feel colder because they more efficiently sap heat from our skin. Wet things feel colder because water and other highly conductive fluids which have wet the skin (and are thus in direct contact with it) are much more efficient in removing heat, thus feeling colder. This is the twofold reason why oil doesn’t feel as cold as water: it has significantly worse heat conductivity, and it doesn’t readily evaporate (as evaporation is a highly endothermic process, sapping heat even more efficiently than a conductive liquid on its own.)
Sorry these facts are actually useful, please leave. ;)
Oh yeah? Well menthol tricks your nerves into thinking they’re losing more heat than they are, so if you dissolve a tiny crystal of menthol in everclear, you can make a tincture to rub on a part of your body that’s sweating, and it will feel naturally cool for about ten minutes, reducing discomfort from both heat and sweat! How’s that for “actually useful”?
This is so cool to know!!! Thank you!
I feel like that’s like “you can’t see or touch the world or experience time, your eyeballs and molecules that never touch anything are just affected by magnetic and gravitational waves and translate that to feeling and experiencing those things”
Like I guess it’s technically true in that perspective, but effectively false
Somewhere bongos started to play…
Is that a Jumanji reference?
If sound could travel through space, from the distance we are to it, the sun would be as loud as a jackhammer everywhere on the planet, all the time.
Are we assuming sound is traveling through space as if it were air?
If it were like sound through water it would be even louder.
Fake raspberry flavour comes from Beaver anal glands.

Whelp… yet another thing to add to my never have again list.
Genuine castoreum is pretty rare in products nowadays, as it’s pretty expensive. Synthetic flavourings are typically used instead
So, it’s simulated Beaver anal glands?
I have many but they only come out when I absolutely do not need them.
Useless knowledge.
When playing Mechwarrior 2 on a Windows 2000 system, make sure to change your video mode to 32bit color.
I’ll throw in a useful tip too!
You can buy USB foot switches for your computer and assign keystrokes and other functions to them.
Almost feels like cheating when you are playing a tactical shooter and can lean left or right and strafe on demand without crossing any controls. Having microphone activation, map, inventory, or any number of misc actions boud to a foot pedal makes a huge difference in your ability to play a game.
Further knowledge about Mechwarrior 2: 31st century combat:
At various stages in the campaigns, you’ll face off against Elementals, escort a Tarantula, and fight a Battlemaster. Through cheat codes, you can add these to the mech lab and play in them in the “Trial of Grievance” free play mode. The Elemental works fine, it functions as a tiny mech, the Tarantula works mostly correctly, but it isn’t 4-legged. It looks like it is but the front two legs are legally arms, they can be blown off and it works fine. Trying to select the Battlemaster in the mech lab will immediately crash the game.
Cheat codes for Mechwarrior 2 were the very, very first thing I searched the internet for.
Dishonorable conduct, Wetnose.
lol the drill sergeant character who spoke almost entirely un-clanlike, other than occasionally using the term “freebirth”.
I don’t know. Sounds kind of useful to me.
Probably more difficult if you have pets
Nah, my snakes don’t really mess with the foot pedals.
The theme song for the game Civilization IV is The Lord’s Prayer is Swahili.
That’s… An odd choice but okay lol
It’s a great song. First video track to win a Grammy.
Oh shit. Imma have to look it up
When Mount Vesuvius erupted, the heat of it turned a man’s brain to glass.
Glass is made of silica. So, nah.
According to the International Commission on Glass, silica is one material that can be used to make glass, but not the only material:
Pigs can’t look directly upwards. Neither can we, when standing on all fours. This is because ours and pigs necks are constructed in the same way.
And according to some weirdos on the internet who apparently know some concerning things from experience, human meat tastes the same as pig meat. Tastes like Pork. But now I’m curious why pork & ham & bacon are three distinctly different tastes & textures if they all come from pig.
The people who got anime to take off in the US are the same people who started the furry fandom.
The Superman symbol was based off of the symbol for a sci fi fan club.
Conventions, and sci fi as we know it, are because of one electronics magazine.
