Barnacles!
The last thing you’d want to come across while walking barefoot on the beach is glass. But what if the glass isn’t sharp at all? What if it comes in the shape of a ball? And it has barnacles latched onto its surface? If this were us, we’d chuck the thing into the ocean, just because.
It’s pretty impressive how marine life can thrive on anything you leave in the ocean. That’s probably not all that great, seeing as how most of the stuff we dump in the ocean is garbage. Given enough time, Mother Nature will take over whatever manmade object or construction we put in her path.
