The only thing more sure to sour a trip to the beach than a shark attack or acid rain is a drink knocked over. Your soft drink or alcoholic beverage of choice, drained into the sand. Enough! Give your drink feet.
Turtlebacks are pretty simple — essentially clawed coasters, that'll dig into sand (or dirt, probably) to give your beverage even footing. This beats the traditional method of grinding your bottle into the sand itself, as some neolithic attempt at digging out a foundation. If you don't want to take any chances, you can snap up four Turtlebacks for $US20. Or just hold your drink for free. [Turtlebacks via book of joe]
