I might be back in Jo'Burg at the end of the month so a meet would be awesome depending on the boyfriend...

Right!
September is over (seeya busiest month of the year!) and October is here. This means I have a a hankering for Pub Trivia!
Applicants for Team Awesome (a.ka. Team Super Tiger Death, a.k.a. Team Trombone Pleasantry) will be accepted based on the quality of random, yet trivial, facts supplied along with a valid suggestion of a venue.
Or, just if we need the numbers...
Anyone keen for Oktoberfest the Micro Brew Trivia Event?
When?
Where when how what who?

All three of you are disqualified.
Yes
I was too lazy to get a random piece of trivia for you, but here is a piece that is especially relevant in JHB today: The average raindrop has a diameter of between 0.5mm and 3mm, and contains approximately 70-300mg of water in a single drop.
As to WHERE the pub trivia could be held, the reason I'm asking you is because I don't know
And for future reference:
Hailstones often grow in alternating layers of rime and glaze, when they are continuously rotated up and down by updrafts and downdrafts. The freezing process repeats itself until the weight of the hail stone causes it to fall to the ground or the updraft weakens enough to eventually end the cycle.
Know of no trivia bars around here.
Rain drops are in fact not that stereotypical tear-drop shape either. As they are in free fall gravity acts equally on all parts of the drop and downwards; surface tension is equal for all force vectors bounded by the surface of the drop, as a result the surface tension pulls the drop spherical.
Same for taps, once the drip disengages from the tap, the drip is tear-drop shaped and takes a moment to become spherical

Well aktuwally, the shape of the raindrop is an oblate spheroid, if we're being technical! Wind resistance causes the section of the raindrop facing the ground to flatten
Surely after a time the water-droplet will reach terminal velocity and all external forces will cancel out; leaving only surface tension to equalise - thus pulling the droplet spherical? :: or is it that the liquid nature of the water doesn't actually allow that and thus it is a constant wiggle between the two - thus making it oblate spheroid?Well aktuwally, the shape of the raindrop is an oblate spheroid, if we're being technical!

(This goes into the category: Things I would like _OTHER_ People to Research :P)
You raise an important question; can you actually claim that water droplets are any shape in a free-fall vacuum? After all we know the vacuum is absolute and therefore below the vapour pressure so the droplets shape (during the testing) would take on a gaseous cloud?! o.O

Source: Shape of a Rain Drop - Weather ImageryShape of a Rain Drop
Rain drops are often drawn in books or shown on TV as being tear drop shaped. In reality, the shape of a rain drop changes as its size gets bigger, and they are never shaped like a tear drop at any point during their life-cycle. Their shape is a result of two things; water surface tension and wind resistance. An example of water surface tension would be the shape water takes as it collects on your car just after it has been washed and waxed. The water globs up and sits on top of the car instead of spreading out into a thin layer. Wind resistance on the other hand, creates a force on the rain drop which causes them to deform and break into smaller droplets. Imagine blowing on a large bubble and noticing the change in its shape. When the wind resistance overpowers the water tension force, the water droplet deforms so much that it splits into two smaller droplets.
Water tension and wind resistance therefore are constantly affecting the shape of a water droplet as it falls through the air from the clouds high above. The water tension keeps the water droplet intact instead of breaking up into many smaller droplets. Conversely, the wind resistance is trying to break the water droplet apart. When the rain drop is small in size, about 1 mm in diameter, it take the shape of a small sphere and is virtually unaffected by the wind resistance. At 2mm, the rain drop is still held together by the water tension but it starts to get deformed by the wind resistance. As a result, the bottom starts to flatten out a bit. At 3mm, the rain drop looks more like a jelly bean than a tear drop, but the water tension still holds it together. At 4mm, the rain drop becomes very deformed and begins to look like it could split in two. At about 4.5mm, the water tension is over powered by the wind resistance. The rain drop is so deformed it creates a large canopy (almost like a parachute) and splits into two or more smaller drops.
During a very heavy rain, these rain drops can break apart and re-combine into large drops at quick rate. So for some of their life time, they can exceed 4.5mm in diameter. Also, if the rain is partially frozen (eg; melting hail or sleet), the size can be slightly larger and the shape more irregular.
So depending on how big the rain drop is, it can be either round or flat(bean like).
Napoleon wasn't actually short, he was about 1.69m and was taller than the average Frenchman in his day.
Well technically the temperature in a vacuum is well below the freezing point of water, so it would be ice, not water. The shape of the ice would thus be dependent on the shape of the water droplet at the point it was introduced into a vacuum? I'm not exactly a scientist, so if you can find research showing what it does, I fully stand to be corrected.
If, however, you're referring to the shape of a water droplet in zero-gravity, well that's dependent on the size of the water droplet. The larger the droplet, the more amorphous the shape. However, water tension in the smaller droplets would probably keep the water droplet in a perfectly spherical shape.
In days long long ago, Popes where required to sit pantless and let cardinals judge their testicles. They used the saying "Testiculos habet et bene pendentes!" (He has testicles, and they hang well!)
Curiosities -- New Internationalist
All of this and no venues?
Think Keg in Fourways has one if I remember correctly
Can phone and find out tomorrow....
Popes pish! The same could be said about Mother and I get nary a sodding mention on the whole damn "New Internationalist" -- bloody conspiracy I tell you!
