Upgrade/RFFoil/WoodsMetal
Wood's metal is an allay with a low melting point, about 60 degrees C. A lot of information on Woods metal can just be found on WikiPedia:
http://en.wikipedia.org/wiki/Wood%27s_metal
Wood's contains cadmium and lead, and therefore is poisonous. However, there are a variety of alloys with similar low melting point. Not all of these are poisonous, for instance Field's metal. The latter is a lot more expensive, but that's probably not a problem since we don't need a whole lot of it.
Where to buy
Wood's metal is sometimes sold under the name 'Cerrobend'. Mari form VDL pointed us to these companies:
