Beach Vault!

For those who are protective when they go to the beach, the Beach Vault is a pretty neat idea.

This will make you feel like Jack Sparrow, looking for Rum on the deserted Island. Tossing the e-reader and iPod in your bag can be a great way to enjoy a day at the beach, but when you add it to your wallet, keys and cell phone that's a lot of valuables to leave unattended when you head out for a swim. The solution, according to the designers of Beach Vault, is to bury them.
