Yup, this bottle opener fires cap(s)! The Spinning Hat Cap Zappa is one cool bottle opener. The Cap Zappa launches a projectile up to 16 feet, and uses the caps it collects as ammo. It’s a perfect conversation conversation starter, and is a formidable weapon for sibling rivalries, office wars, and classroom prank battles. It attaches to your keychain, allowing you a super quick draw in case you find yourself in a duel with Alexander Hamilton (sorry, lame joke). It only measures 6.5” x 1”, giving you the power to launch surprise attacks on unsuspecting targets.
