  2. strange rocks wash up on beach... what are they?

    I found these rocks washed up on New Smyrna Beach and ordinarily I wouldn't have picked them up, but they all had a signal of 80-85 on my detector..... Can you identify what these are? They registered in the are of silver (and aluminum cans)..... Just Curious because we usually don't get hot...
