Man, some people.
It's not a recreation of the song in Mario, it's an Automatic Mario set to the song. It's fun and obviously done by someone who loves the song. Take a bit of joy in life sometimes.

There's a simulation you can play around with here, and some explanation of the maths behind it:

Most of the plastic has broken down into pieces smaller than 5mm across, and it's very diffuse. It's not like there's an actual island of rubbish floating in the Pacific, at its densest you still only find a dozen or so pieces of plastic in a cubic metre of water.

It doesn't sound like a lot, but it's especially bad for creatures like whales that feed by sifting through vast quantities of ocean to get enough food. Small filter feeders like shrimp are also affected, and being at the bottom of the food chain it means the plastic also gets ingested by any animal that eats them.

Boiling point lowers as pressure decreases. So at sea level the boiling point of water is around about 100˚C, but at the top of Mount Everest it's more like 70˚C. There's no real value for the boiling point of water in a vacuum, because it would be a gas at any temperature.

Edit: Actually, you can get solid water at very cold temperatures in space, but as you heat it up the water would transition straight from solid to gas, so it has a sublimation point instead.

The microgravity experiment was probably done in a shuttle or the ISS, which are pressurised to about the same as sea level so that it's comfortable for the astronauts.

That IQ table gets posted around so much, I'd be interested to see some real figures comparing states.

I can't wait for the follow up advert about alcohol, where the party with [Sociable] and [Relaxed] gets crashed by [Angry], [Violent], [Clumsy], [Nausea], [Memory Loss], [Cirrhosis], [Vomiting], [Depression] and [Death].

And then we're reminded to drink responsibly.

It looks pretty awesome, but to me it seems as if the balls slow down too much. No wheels on them at all.

CHEESE AND WINE

What? Ahh!
Don't inflate your eye!

Charliem: You can turn off *electro*magnets. And even then certain types will remain magnetic. You can't turn off a magnet.

He's got some interesting points, it's just a shame his voice is insufferable.

I refer you all to Buttlord GT:

The pole seems a bit too thick for some of them, they can't seem to stay on it. A couple of them manage nearly the whole thing, but most of them can barely get past the start. Maybe if they tried a different position, it'd go easier.

The stunt I mean.


... sorry.
