Acid Trivia

The digestive juices of crocodiles contain so much hydrochloric acid that they have actually dissolved iron spearheads and 6-inch steel hooks they have swallowed. Yet crocs don’t take Rolaids, as far as we know.

So I'm wondering ... is this an effective way to dispose of scrap metal?  Also wonder if they've analyzed the poop of crocodiles.  At any rate, we must never go near one!!!
