i've done 72 hours before! not so easy. good luck with your attempt.

Yeah thats true. Its because the air is stored at very high pressure (300atm?) so if its a 10litre tank when filled it has the equivalent of 3000 litres of air in it.

yeah it basically destroys and denatures everything living(bacteria, mold, us animals, yes even that cute little gerbil you got for christmas) or based on proteins(virii etc.) it isn't used on animals for that reason. it would also kill us.

could probably be done with some sort of expandable frame. but that would limit the lower and upper limits of the balloon. would also make it too heavy.

yeah its possible but only in the inner solar system. inter galactic travel will require more than solar panels. also nobody could survive the trip. nearest major galaxy is 2 million light years away. thats 2 million years. thats how long ago the earliest humans fell out of the trees and couldn't be bothered climbing back up.

wonder if you could make ship hulls out of it. probably need a lot of ballast to keep it stable. also probably not good for passenger ships but what about barges or container ships.

take a container(about a litre or 2 should be ok) capable of withstanding sustained pressure, zero a scale with the unpressurized container, then pump lots and lots of air in. if you attach a pressure guage and do some maths then you should be able to calculate the weight of air with a bit of accuracy.

Nope. if it does i'll probably be sleeping so i won't care.

Now try it on hard with no cheats then you'll be on par with me time limit: 3 days.

the black hole has exactly the same gravitational pull as the star. its just more concentrated because it is far far far far more dense than an atomic nucleus. and since gravity works on a 1/r^2 relationship and the event horizon(for all intents and purposes the surface of the black hole) is really small the light can close enough where the force of gravity is HUGE.

1 word - equilibrium. changing the temperature will shift it. i can't remember the enthalpy values off the top of my head but if its endothermic raise the temp. if its exothermic lower the temperature. or maybe the salt is acidic, or the solution is saturated. if its the former then the HNO3 is used up, if the latter try adding more water. Do you not need aqua regia to dissolve silver or is it reactive enough for nitric acid to do the job(I can't remember)

YHNIHFTCB - YT2095 Has No Idea How Fun This Can Be. Ok so tha one wasn't from slapping the keyboard but i doubt YT's was either. at least not from one slap.

I thought routers were built for routing data, hence should be able to handle heavy traffic(although i suspect it would be no match for a busy road )

Good point.

LoL.

Enjoy coughing up your lungs if you inhale what you think is the oxygen.

sigh... another kewl. Although... I was one briefly, I seen explosions on T.V. picked up a chemistry book to see how to make explosives and then fould out that there is a lot of even better stuff you can do and it doesn't involve explosions or anything. so i was a kewl for a bout 2 days and 5 hours. acids are relatively boring compared to some of the millions of other interesting chemicals out there.

Fake boobs, a botoxed face and liposuction don't make women look like they were assembled by a severly brain damaged rodent. I wish i only had a mono speaker instead of 5.1 dolby surround sound. Why the hell does creationism not get more respect from scientists. there is tonnes of evidence to back it up including that superbly accurate book written 2000 years ago called the Bible.

Excrement can burn if you dry it out enough.also what about the bacteria that live on it. they even produce methane out of it.

hmm... in the chemistry labs there is a 55:52 ratio of girls to boys. from this we could say that women are pretty well represented in some areas.

yes its all a hoax. british airways employ engineers who are pretty clued up on physics so they know that its impossible (at least within the next 100 years unless aliens show us how). If soil had that much rare earth metals in it it would already be feasible to process them out by standard methods. And soil has been analysed in spectroscopes, mass spectrometers, chemically. we know the composition of soil quite well.

Suddenly about 30 pages of key commands for various games and simulators make sense now. i used to just make my own keymaps for functions. amazing what you miss.

Never knew you were into that sort of stuff Phi. Is it fun?

"Wow! who knew that the manufacture of toothbrushes could be so exciting!" "I really want an Apple II for christmas, they're so fast and the graphics are great!"

how asymmetric? just a little bit or very?
