Giant Inflatable Beach Ball
In a sweeping display of calling a duck a duck, the makers of this plastic sphere that balloons to 10 feet in diameter when injected with air have named their creation: Giant Inflatable Beach Ball. And truly, when I look at it, ball is the first thought that comes to my mind. Well, balls really. As in, Holy balls, this thing could take out half the kids who'd want to play with it. Never mind having a beach, or any body of water at all for inflatable giant enjoyment, just toss this thing in the backyard during the next BBQ or birthday party, and let the human bowling begin.
Naturally, the manufacturer's (meaning the manufacturer's insurance company's) recommended age for Goliath beach ball use is 18.
