It is always good to be prepared in life, and for those who want to spend plenty of time by the beach, you might want to check out the $149.99 12ft Giant Inflatable Beach Ball. That is a crazy amount of money to fork out for a beach ball, no? Since there are always plenty of annoying kids by the beach, the 12ft Giant Inflatable Beach Ball is the ideal tool to mow down annoying kids on the beach. Obviously, for something so large, it takes plenty of hot air to fill, and an electronic air pump comes across as highly recommended to pump it up, as using your lungs would result in your lungs bursting.
