Chemmunity: a collaborative chem project where no suggestion is too dumb

[Bologna Prime]

Chainsauce, a mixture of metal teeth and scrap suspended in oil.

While in your system, any actual arms will fall off. If you have no arms, the reagent will attempt to place chainsaws on your stumps similar to how super hairgrownium will repeatedly give you moustaches. I guess the same effect could be achieved by just replacing arms with chainsaws, but I don't know which would be easier to code.
