A cannon with no fuse? Simply submerge this award-winning water cannon in pool or pond, grasp the two handles, and pull. You've just fired a one-inch stream of water as much as 30 feet in the air. Science buffs will learn that the phenomenon of fluid gaining momentum as it flows through a decreasing diameter is known as the "Venturi" effect. It's phenomenally fun - active, interactive, and trusty as Ol' Faithful - no parts to break; no batteries to add. Assorted colors ~ each sold separately. Ages 6+
