Abstract: A manually operated toy pneumatic launcher for launching a ball projectile. The pneumatic launcher has a housing with a first section and a second section that move relative to each other. At least one handle extends from the second section that rotates through a range of motion. A base tube is affixed to the second section. A launch tube is affixed to the first section.
