The noise made when clicking your fingers is the sound of the finger hitting your palm not the finger and thumb rubbing together.

You only need a maximum of four colours to make a political map of the world without any adjacent countries having the same colour
Is this still true when considering exclaves and colonies that aren't connected to the countries' main landmasses (e.g., Sint Maarten as part of the Netherlands)?
No, the 4-colour theorem only applies to a surface which is simply connected :roll:

Shit. Why has no-one mentioned this before? A quick couple of clicks just now suggest you might be right as well.

Yes, I love this one! I never used to be able to click my fingers until I figured this out. Nowadays of course, my finger-snaps are much sought-after by all the top popular music artistes and have featured on many hit records, none of which I can bring to mind presently, for some reason.

That said, I can also produce a reasonably loud noise without using the palm, by forcing the thumbnail back (edit: actually I'm forcing it forward, come to think of it, i.e. towards the palm) and releasing it (whilst ensuring that the finger used doesn't impact the rest of the hand). It's a different quality of sound, but it's similar. I don't have very long thumbnails though; it would be interesting to hear the sound made using this technique on e.g. a two-inch long nail. Or maybe it would just break off? I think I'll try to grow the one on my right thumb in the interests of research.

What am I missing here? Why on earth would anyone think a finger and thumb rubbing would produce a sudden sharp click sound?

I think it's more of a case of "I never spent any time at all thinking about how the sound is made" rather than "I believed the sound was made in a different way".

So this was the most pressing thing that needed a reply in two months?

I meant the fact that several people also seemed to agree that this was groundbreaking news.

Isn't the whole point in these things is that they aren't groundbreaking, and people are shocked by their having felt like they were groundbreaking discoveries only for a moment's thought to lead them to believe that no, they're actually "REALLY obvious"?

The only difference with the finger snapping is that most of the posts in these threads have been people making these groundbreaking discoveries and then coming to realise that they aren't groundbreaking away from the forum, then later on posting about it here. With the finger snapping Mark's first post fits this and then you're seeing subsequent people doing the groundbreaking-no-actually-really-obvious thing in almost real time on the forum.

At the risk of incurring the wrath of Mr Corby, I've only just realise the cracking sound made by a whipcrack is caused by a small sonic boom.

I've just realised not everyone watches QI. What's not obvious though is why they don't.

The smugness rating is too high.

In Arrested Development, why Maeby's alter ego is called Shirley. It took until my 4th rewatch to get this.

I used to think that your cholesterol level was the level of build-up in your arteries, whereas it's actually just a measure of cholesterol in your blood. What I was thinking of seems to be atherosclerosis.

The theme tune to Points of View is When I'm 64....because of the lyric.
