Never wash your clothes in supercritical water. "That jumper makes you look fat", "those jeans went out of fashion years ago!" etc.
If I had a bucket of water at its triple point, what would it look like?
By the same line of reasoning, what would a bucket of super-critical water look like?
The bucket of super-critical water should look like normal water. Though if you disturb it slightly, such as dropping a few grains of salt into it, or bumping the glass, it will suddenly boil over, concentrating on the crystals or the point of impact. This tends to make it violently boil pretty much from every depth of the bucket at once, and it is not fun to be close to it. (From personal experience when trying to rush boiling a beaker of water in AP Chemistry when a lab was running late)
Er, that's superheated water. Supercritical water is when liquid and gas are the same thing.
A friend asked me a common question: How much does Jupiter weigh?
I can't remember the details of the answer to that question, but how do I explain it as close to laymans terms as possible?
If you weigh 100kg on Earth, you would weigh a little under 17kg on the moon, assuming you stayed the same mass.
If you are 100kg on earth, you're still 100kg on the moon, since kg is a measure of mass, not weight.
Pop Quiz:
I'm right now holding something that weighs more on the moon than it does here.
How can that be, knowing that moon's gravity is ~1/6 that of Earth....?
What am I holding?

contre said:I'm guessing a buoyant gas.
I think a helium balloon would weigh less on the moon as well. Weight is mass times gravity. Mass is the same, gravity is less too.
Would a smartphone, such as the latest android or iphone, theoretically work in the vacuum of space (granted the sound from the speakers would have nothing to propagate through) by itself, or does it require an atmosphere in order to work, or at least some sort of protection?
