Is it true that if you feed calclium carbide to a duck (or any other of out feathered friends) it reacts so violently with the powerfull stomach acid that the duck physically explodes ?
From what I've read on the subject, it's fair to say you'd kill it and burn out its insides. Found one source that said the substance was "incompatible with hydrogen chloride" and "reacts violently with water". So, it almost certainly could.
