that site is garbage, they failed to state gun deaths vs. car "accident" deaths, vs. drowning, vs. chances of getting struck by lightening. not only that, but how do you distinguish what is a justified shooting or not...only 300 shootings were justified? i think not, given that every night on the news i hear about some woman raped on a college campass, or some other crap like that...there are well over 300, however, its because of out screwed up courts system that these are not classified as justified shootings. i've heard cases of guys breaking into houses and then throwing the owners to the floor, then the owner throws boiling water on them or some other crazy thing, and the owner actually gets sued for it. because he could have "fled" his house. what bull crap is that? if someone breaks into my house, they're gonna find a 12 gauge between their teeth and nowhere to run. just think, in MA even pepper spray is banned without an FID card which costs 200 dollars and a couple weeks to obtain. and they wonder why women are still being raped...because they can't defend themselves, the attackers have nothing to worry about. but, if everytime they attacked they got sprayed, they'd probably A. stop attacking, or B. put a gas mask on...and that would eliminate at least 1/3rd of attackers. its common sense. but hey, if you want to join the anti-gun rally, why not march up to diane feinsteins door and check out her revolver...i guess its quite nice.

daaaamn, thats small....

in america, this company has a NICE selection, cesium, rubidium, potassium, mercury, gallium...etc...and all the compounds... http://www.espimetals.com no pricing on the site, but by email they'll quote you, the biggest ampoule is a 50 gram for most metals, thats a pre-scored ampoule, the biggest break-seal is a 5 gram. which for cesium would probably be close to 700 dollars. heh.

yeah YT, i've seen the reaction and how much vapor it produces(HF vs. glass) its definately no joke, as one wiff is certain death. in fact, there was so much vapor, that even next to a window, it filled the room and the proceedure had to be evacuated before it found its way through the double filtered gas mask that was being used. i'd say it aint no joke.

now thats cool.

well, how low is hydroflouric on the Ph scale? i saw it on http://www.power-labs.com, it ate through a glass vile in under a minute, and would tear your hand off pretty fast.

well then...have a ball boris. just dont get it on you, because that would REALLY suck. lol. post some experiments when you've documented them:)

you might want to consider something a little bit coarser...something recommended for rifles...the stress from the QUICK burning mealpowder can blow your "launcher" apart. and thats not good. especially if you're using steel. i'd test without any projectile in it.

D2O is heavier than water, therefore denser, therefore it can absorb much more heat, therefore its boiling point is higher, therefore its better for cooling.

you wont need much to go 20meters...with BP, its highly recommended to use steel. not pressure rated PVC...

what would happen if i dumped some cesium hydroxide into hydroflouric acid? one of the strongest bases vs. one of the strongest acids...

well, unless you have a dewar flask, proper ventilation(asphyxiation), gloves and proper work materials to use liquid nitrogen with...i'd advise against it. but, if you really want to check it out, definately get a dewar flask. lox can be supplied by the same people with the liquid nitrogen. and the easiest way to make it is to dip a container of oxygen into liquid nitrogen.

boris, most compressed gas companies will give you as much as you want, the only thing is though, they dont give it to you unless you have a suitable container. like a dewar flask. and those are like...100+ dollars. also, dont store it in anything with a closed cover. because liquid nitrogen turns into a gas and it will make your container a bomb...lol. 100ml of liquid nitrogen will evaporate within an hour, so you have to use it quick...check out these http://www.power-labs.com/lnprop.htm http://www.power-labs.com/ln2fun.htm http://www.power-labs.com/ln2demo.htm

must be shipping via usps, i was just wondering what UN's shipping preference was.

hehehe, good to know... so can you explain to me the coloration in the salt solution? it was dark green on top, except around the cathode, which was strange, because i'd figure that even though only half the amount of oxygen as hydrogen is produced in the same time, it would still bubble, which it didnt. anyway, so it was dark green except around the cathode, and then it was yellow underneath that, and then it was crystal clear on the bottom. which, it all started as a fuzzy mix due to a large quantity of NaCl. can you please explain what these colors were?

thanks YT

condoms...thanks man, thats one i havent thought of! store clerk~condoms huh? me~yeah, im doing an experiment for science class... lol

how is it being shipped? alum powder is hazmat. ups charges 20 dollars per order. but the us postal service(usps) will do this order for free, as long as its under a certain limit.(lbs)

so what if i seperate the anode and cathode, like, place a piece of rubber or plastic between them for the length of the bottle, and then diverted the hydrogen to a seperate container. since the OH- would be attracted to the anode, the H+ would bubble near the cathode and be diverted, however, could i do this just by blocking off the two above the water? since the two gasses wouldnt be able to reach the other side? also, in electrolysis, how much pressure is made by the gasses, mainly hydrogen, would it fill a deflated balloon? assuming we're at sea level?

usps? or are you paying ups a 20 dollar hazmat?

wouldnt sodium also be produced if i was using an NaCl soln? is salt a necessity in electrolysis of water? i know it makes the water a whole lot more conductive...but can it be done without the salt? also, where would i get sodium hydroxide?

whew...i thought i killed a couple thousand more braincells...that inhailing helium when i was a kid really did me in...

i have but one question after JUST performing this experiment. is hydrogen gas poisinous? lol. after about 4 minutes into the electrolysis i got lightheaded and i could hear my heartbeat. so i stepped away from the experiment and i felt fine after a minute. weird....anyway. this definately works. after about 20 minutes, squeeze the bottle into the balloon. it makes a good bang and a mediocre ball of flame...i tried to emulate the results of my professor, but his balloon was much more volatile. not to mention, my balloon didnt float too well. too much oxygen? maybe i could tape a milk jug on the top of the bottle. that would make for a better holding tank.... also, the water formed 3 layers, one really deep green layer at the top, a yellow layer int he middle, and then a crystal clear layer at the bottom. and a couple chunks of black floating around. could this be because of the table salt that i used in the solution? i think the black chunks were a protective coating on the screws i used. other than that, it was pretty exciting. also, i left this thing going for probably 10 minutes....would that be a sufficient amount of hydrogen? how much is produced in ci in a matter of 1 minute? in other words, how long would it take to fill that coke bottle with hydrogen doing electrolysis?

oh...lol. sorry boris. west marine is american, im not sure if they are international. but i know they are american.

5614, my professor blew up a balloon filled with hydrogen, it works. it wasnt like an m-80 bang, but it was a slight pop and a huge ball of flame. if you light a match and drop it into a bottle, it sounds like...4 times louder than a shotgun, and, IF the bottle actually breaks, the most you'll get is a strong gust of expanding gas. the hole in the bottom is to vent the oxygen. just above the water line. so you can get fairly pure hydrogen using this method. and yes, the screws are the electrodes. good observation.
