Gear: Pneumatic Rocketry

My cousin's kids were playing with an Air Hogs pneumatic rocket during their stay at my parents place. It is an amazingly simple yet fun toy. My brother and I even had a go pumping it up and launching it. About the only way to hurt someone with it is if they're standing on top of the rocket when someone fires it off. When playing with careless 4 year-olds, that happens more than you might think. But even then I think most of the injury would be to the person's pride. Really, it's fun for all ages.
