United Nuclear -- fine purveyors of Van de Graaf generators, neodymium magnets, lasers, uranium, and other useful supplies to hobbyists and paranoid enthusiasts -- is being threatened by the US Consumer Product Safety Commission (home of Kidd Safety) with criminal action for selling certain products to people without an explosives manufacturing license. And just what sort of dangerous substances are on the CPSC's list?
Not sell, give away or otherwise distribute any of the following Metals for which the particle size is finer than 100 mesh (or particles less than 150 microns in size) to any recipient who does not possess a valid manufacturing license for explosives issued by the ATF:
Aluminum and Aluminum alloys
Ostensibly the CPSC is concerned about the use of aluminum powder in the manufacture of illegal fireworks. However, given their obsession with government approved helmets, it's safe to say what they're really concerned about is the powder being used as an undetectable anti-psychotronic coating for common head wear.
Just another step towards the eventual outlawing of private aluminum ownership? Undoubtedly. Stockpile while you can.
