Ahh, brings back fond memories... trying to persuade my chemistry
teacher to make 18M Aqua Regia (he never did, but I had a go when
nobody was looking, just 4M, succeeding in disolving part of a
sink grill. ), electrolysing just about anything I could find in
my own expts, making HCl and hydrogen gas, fun with sodium chlorate
and sugar (plus sulphur, charcoal and sawdust), high voltage
transformers and salt solutions on wooden blocks, etc... those
were the days! 8) Young & care free.
lol yea I'm a pre-med student so I really had an appreciation for the science depth which this article contained. It combines my two favorite (tech and science lol) so this article was a win!
As MU_Engineer was saying though, these reactions can be very dangerous! Whenever we work in the lab, there are a number of precautions that need to be taken and he pretty much listed them all. First day of labs is always safety training so please take it seriously.
You guys may not realize this, but being preemptive is one of the safest things you can do. At most universities they won't even let you enter the lab or participate in experiments if your wearing shorts, sandals, long hair, etc. And a lot of times even that isn't enough! Fume hood's is a pretty big one as well as all the protective gear.
Most important safety feature is the eye and shower wash though. A lot of things can go wrong, but many are recoverable. Eye damage is rarely one of them though so please be careful
am disappointed T_T, i thought that i'll buy the car of my dreams tomorrow.
never the less, interesting article, never thought i'd see it on toms.
EDIT: last pic shows a ruler with digital number, and for some reason that's funny ^_^ lol

[citation][nom]anamaniac[/nom]That was actually somewhat interesting.Though just for an idea on the scale of things...Gold was worth ~$450 per troy ounce in 2005.There are ~29,167 troy ounces per ton.318 tons of gold equates to $4,173,797,700.4 trillion dollars in a single year, back in 2005.With gold closing at $1185, and growth in the electronics industry, can you imagine what kind of numbers are involved in this year?[/citation]
Shame on you for wasting what I presume to be perfectly good computer components on a frivolous experiment. A lot of people are still living without computers these days, and good nonprofits are out there taking donations and building great desktops for them. Those motherboards could have helped provide a disadvantaged person with their first computer.
