This toy air gun uses the same patented design as the classic toy that kept children amused with fun-filled play in the 1950s. It uses air-powered pump action to safely fire up to 15 ping-pong type balls (one at a time or in multi-shot bursts). Accurate up to 20 feet, each ball makes the famous burp sound when shot. Because it’s powered by pump action instead of batteries, it provides hours of uninterrupted fun.
