If you’ve ever suffered from heartburn or stomach acid, you know painful it can be. What most people don’t realize is that the acid is powerful in more ways than just causing discomfort. The stomach acid in your body is strong enough that it could destroy metal. On the pH scale from 0-14, 0 is the most acidic, 7 is neutral, and 14 is the most basic (non-acidic). Stomach acid generally falls somewhere in the 1-3 range, which is the same area in which you would find battery acid. Who needs superpowers? Your stomach acid can melt metal and eat through wood.
