Why don't lit candles set off fire alarms?

Because fire alarms don't detect fire, they detect smoke?

Why do large company IT systems not let you change your desktop background? What it the benefit of this? Is there any? Other than some dodgy photos I suppose.

I was frying something at home, pan on full blast and very hot oil, I washed my hands, couldn’t find a towel so I.....shaked the water off my hands? Can’t find the word....I just moved my arms up and down hard to get the water off into the sink and a few droplets of water went into the pan and boom, oil started spitting everywhere with lots of noise. It wasn’t a pleasant experience, I shat myself n rushed away as it was pretty violent!

So, my question is

What would happen if you had an average sized swimming pool full of boiling oil and 500 liters of water dropped inside

You would get a violent explosion.

The water would turn to steam and shoot into the air, carrying bits of oil with it, when the oil hits oxygen, boom.

In the USA they have big deep fat fryers designed to fry whole turkeys (not sure why, but they do). the fire department produced a video of what can happen:

The reason why is that deep fried turkey tastes epic!

We did it for Thanksgiving this year and because it was so tasty, we did it for Christmas too!

Are there any species on the planet today, which directly evolved from a species that also exists today?

Man and monkeys?

Nope - our common ancestor is no longer around

Probably, yes, although genetic drift makes it debatable. I think you would be looking at rapid speciation under unusual conditions - island finches, for example. Or possibly simple animals living in very stable habitats. Nematodes in caves, perhaps.

I think he means is there a species whose ancestor is still around, not who share a common (extinct) ancestor. Whales and Hippos have a common ancestor, but haven't evolved from each other (I don't think).


This has happened (very) recently, but it's not as exciting as you'd hope:

The Horshoe Crab is damn ancient and there are four species, but I'm not sure if they're an ancestor of modern crabs or not.

Corporate policy. Corporate look and feel.

They paid some company millions for that corporate logo, look and feel

Yes, yes it would.

In fact, here is a reasonably effective way to clear your nose if you don't want to sniff all the time, and dont have a tissue nearby:

Hold your breath.
Pinch the top of your nose
Gently shake your head side to side, for 15-30 seconds,

Your body will naturally clear whatever snotty blockage it has built up to allow you to breathe once more.

As others have said, a blocked nose is usually inflammation rather than mucus so this isn't true sadly. Funny how old wives tales are still popular though despite better education and understanding.

Why can't actors salute properly? You're playing a soldier, act like a soldier.

Sake.

Did you just watch the new kingsman film? There's a scene where Colin afirth, supposed ex army officer, salutes.

Like Benny Fekin Hill used to do....or even worse!

Yes, that's what I'm asking.

A case where distinct species "B" can be directly attributable to having evolved from distinct species "B" whilst species "A" still walks (or crawls) the earth.

That entirely new species of bird seems to fit the bill (pardon the pun).

Is it just me, or do modern higher definition TV's have wierd image properties that make them look "wrong"?....

As the owner of a shonky tv whenever I see a show on a large fancy HD tv there seems to be some uncanny valley action going on.

They aren't different species. Just different colours.
