A Swiss 100 gram black powder container.Switzerland is the only country in which it is lawful to make your own black powder, as only black powder for blasting purposes is covered by laws and governmental decrees. In Switzerland people can freely purchase black powder in gun shops for use in firing historical rifles. The buyer must merely inform the vendor as to name and address. The Swiss pyrotechnics artist Roman Signer has used this loophole in the laws to create an explosive "installation" consisting of several miles of fuse wire and heaps of black powder aligned beside a railway line.
