YT2095 Posted June 29, 2005 Posted June 29, 2005 it`s important to remember however that these 1970s early 80`s flash bulbs used a plastic coating of a high melting point to encapsulate them, remove that and the glass would shatter!
jdurg Posted June 29, 2005 Posted June 29, 2005 Many of those glass bulbs used a fine magnesium wire that was sealed inside an oxygen rich atmosphere. I actually don't recall aluminum being used at all.
the tree Posted June 29, 2005 Posted June 29, 2005 no it isn`t!Out of curiosity, what is used in flashbang grenades then?
YT2095 Posted June 29, 2005 Posted June 29, 2005 Out of curiosity, what is used in flashbang grenades then? and of course I`m going to answer that and break the Hazardous Materials rules here, Naah, Nice try though!
the tree Posted June 29, 2005 Posted June 29, 2005 That really wasn't my intent, and I wan't going to try and get hold of any either. Fair enough though.
EL Posted June 30, 2005 Posted June 30, 2005 Out of curiosity, what is used in flashbang grenades then? Very easy indeed. For very white flash bang grenades: Add a cup of corn oil to 4 cups of corn and a tea-spoonful of common salt. Heat in an open pan while mixing thoroughly, using a wooden spoon at arms length. Get ready to dodge the small white flash bangs.
H2SO4 Posted June 30, 2005 Posted June 30, 2005 i read somewhere they used zirconium (sometimes) in flash bulbs.
EL Posted June 30, 2005 Posted June 30, 2005 Most flash powders were based on magnesium and potassium perchlorate, which gave a light rich in blue and UV, suitable for early emulsions that were only sensitive in these regions, but when orthochromatic and panchromatic plates became popular, strontium and barium salts were often added to increase the amount of green and red light. Other metals such as aluminium, zinc, cerium, zirconium and thorium were also used at times in place of magnesium; aluminium gave slower combustion and the cerium mixtures less smoke. They are still very hazardous. Modern Xenon stroboscopic flash bulbs are the best if it was photography that was originally intended.
akcapr Posted June 30, 2005 Posted June 30, 2005 flash bangs contain ammonium perchlorate and magnesium.
jdurg Posted June 30, 2005 Posted June 30, 2005 Perhaps too many hazaradous materials and explosives recipes being posted? (One Hazmat violation = 15 points).
H2SO4 Posted July 2, 2005 Posted July 2, 2005 akcapr, Flash Bangs? If your referring to the little things you chuck at the ground, those have silver fulminate in em.
weldermanx Posted July 3, 2005 Posted July 3, 2005 i guess i should have read the thread more carefully, im not posting lies. a haldf a kilogram of magnesium and a liter of silver nitrate burt a shadow ontot he wall... i have pictures i can email or send via mail. they arent my shadow but its a flash burn im very sorry about all this its hard not to exaggerate whne you are online. im just 13 and want to be noticed:D
weldermanx Posted July 3, 2005 Posted July 3, 2005 you can actually do what i did witha camera and a projection screen.. and i apreciate it if you lay off my back untill you see the evidence thats its BS... try it yourself if you dont belive me
akcapr Posted July 3, 2005 Posted July 3, 2005 akcapr, Flash Bangs? If your referring to the little things you chuck at the ground, those have silver fulminate in em. no, the flash bangs cops and swat guys use

H2SO4 Posted July 3, 2005 Posted July 3, 2005 hey EL, i think i hit reply, and then lat my computer idle and came back a few minutes later, meanwhile, you replied, and i clicked submit, so everything got screwed up. I was replying to AKcapr's post.
EL Posted July 3, 2005 Posted July 3, 2005 idk why do you ask I was just curious, but it is good that you do not know, or it might be even better if you never knew.
H2SO4 Posted July 3, 2005 Posted July 3, 2005 OK "hygroscopic acid" that explains it then. Im not very fond of being called a hydroscopic acid EL. Now that i think about it, i am very hydroscopic ( i can create water where there is none (i.e. the sugar +H2SO4 reaction)).
akcapr Posted July 3, 2005 Posted July 3, 2005 hydroscopic means absorbing water, not making it. and by the way derek, flash bangs are like grenade type things that dont fragment but just make a bright flash and alot of noise which cops use to like "stun" ppl for a while like right before entering a room.

Now that i think about it' date=' i am very hydroscopic ( i can create water where there is none (i.e. the sugar +H2SO4 reaction)).[/quote'] LOL. Not hydroscopic, it is hygroscopic because H2SO4 is a hygroscopic acid that is very thirsty to water. In Lab, we used to make it like a mantra: Never add water to Conc. H2SO4, always add Conc. H2SO4 to water. Did you get it? N. B. Never meant to hurt your delicate acidic feelings.
