As a licensed pyrotechnician, I can buy aluminum powder and magnesium powder too . . but why have the Homeland Security teems see me become a blip on their radar screens? That's cool Joe :thumbs: but you live in the US . Also you can get it from eBAY and you don't need a licence . Too bad they only ship within the US:p |

| 603149 | 2007-10-20 09:35:00 | You know to be honest all I want to do is to make a little thermite to see what it's like - I don't want to make explosives or anything like that (I don't even know how:p). But I was thinking maybe aluminium foil in coffee grinder? Or dissolve aluminium in HCl to form AlCl3 then displace it using Mg? Hopefully you would get small particles of Al that have formed and then all we need to do is filter it with filter paper. Would that work do you think? :illogical So you did not to want to make paint did you? |

Too bad they only ship within the US:p That has to be a mistake listing there . . aluminum powder is not only a pyrotechnic device (the colors in aerial fireworks) but makes a really powerful explosive that, when mixed with the correct other chemicals, is along the lines of C4 in explosive quality and expansion . It is a controlled substance . . . . . . . controlled by the Homeland Security Act (Martial Law) and transporting it in a small quantity MIGHT be legal . . just don't cross a state line with it or mail it or have more than a set amount in your control . For instance . . having fertilizer and diesel fuel in your possession is illegal too . Transporting even means to move a substance from one end of your workbench to the other end . It's a technicality, but grounds for arrest . If you want to see a really neat thing, just set an old Volkswagen engine case on fire . . yes . . it can be done . . . but DO NOT LOOK AT THE RESULTING BURNING . People use them (VW cases) as signal fires when they are boating at night and there's not enough shore lights to navigate back to their point of departure . It will light up the night sky for a mile around . It's the magnesium/aluminum alloy that does it . People have died trying to grind up the case into powder . . . so don't even consider doing it . :dogeye: |

| 603154 | 2007-10-20 18:09:00 | I must admit that I have carried out the thermite reaction several times myself on a small scale with no problems. A small amount in sand, in an icecream container set well away and ignited by a Mg fuse. Very impressive display. Also have carried out the chromite reaction with similar results. This was when I was teaching secondary school and before they brought in lots of regulations regarding experiments that couldn't be justified in a school environment (like Na in water etc). I would not advise anyone playing around with experiments that they know little about although there seems to be plenty of info out there to access methods. Just look at the sparkler bombs at Guy Fawkes time. This alone makes fireworks fun. Bugger the rest of the fireworks, just look forward to the annual sparkler bomb at the end of the night! |

| 603156 | 2007-10-20 19:19:00 | Watching a panel beater attempt to gas weld an early mag wheel and then try to put it out with a CO2 extinguisher was quite a memorable experience. It brightened quite a few people's day. Same panel beater as a lad had ground up a few VW cases with a hand cranked bench grinder and no problems occurred at that stage. When his father went out to sharpen a spade there was a bit of a kerfuffle as a spark found a smidgin of magnesium dust, which rapidly communicated with other dust on every ledge in the shed. A young lad had trouble sitting for a day or two after that. We had to find another source of "firework improver". |
