If you’ve ever been to the beach, chances are you’ve spent some time digging or looking for seashells and shark teeth. Did you know there’s actually a name for what you’re doing? It’s called beachcombing. Beachcombing is the act of searching the sand for nautical treasures. It’s a popular pastime for beach fanatics, so if you have a hunt that yields few treasures, you’re in luck, the tides change all day, sweeping the sand with new goodies to be discovered.
