doin a quick bit of research while waiting for the day to finish (trans: working), I found that the chemical composition of Egg shell is mostly Calcium Carbonate (CaCO3) and that this can be effectively dissolved using many common acids. So putting an egg in vinegar (acetic acid) for some time would eventually dissolve away the shell (which is technically not _breaking_ it).
.... any others?
EDIT: saved by the common brainfart
the problem with Sulfuric is that you have to be able to eat the egg itself afterwards ;)
