Even if you don't like gambling, this will put you on the edge of your seat (oddly enough). It may look like lines that are drawn in the sand, but it's actually a marble raceway that's 750-feet-long. Digging for hours in the sand just to race marbles might sound like a terrible way to pass an afternoon... But just watch -- this is oddly hypnotic. It's time to place your bets -- and watch the most oddly satisfying race ever. So, if you ever find yourself bored at the beach.
