I heard a crime scene investigator say he once found a body in a bathtub. The person’s head was under a drip (from the spout or shower head, I do not know) and, according to the cop, the constant drip bored a hole through the guy’s head.
Unfortunately I was eavesdropping and didn’t get to ask any questions.
First, is this possible (yes, I’m familiar with water erosion in general)?
Second, how long would that take? How long to bore through just the skin? Just the bone? Skin and bone?
