An automatic, rapid-firing toy gun is powered by a fast moving air stream. The toy gun is simple in design and does not require a lot of effort and time to fire the projectiles or to load the projectiles between firing. The toy gun includes a barrel, a fan, a loading chamber, and a trigger. The barrel has a forward end, a rear end, and an inner passage between the two ends. The fan is arranged with respect to the barrel to direct an air stream through the inner passage from the rear end to the forward end. The loading chamber is mounted on the barrel and has an opening directed into the inner passage. The loading chamber is sized and shaped to hold a plurality of projectiles and the opening is sized and shaped to sequentially release the plurality of projectiles into the inner passage of the barrel one at a time. The trigger is electrically connected to the fan. Pulling the trigger causes the fan to drive a large volume of air through the gun barrel and the air stream to accelerate as it travels through a narrow passage of the gun barrel. Projectiles sequentially fall into the air stream one at a time and are quickly released from the gun as the air stream accelerates through the gun barrel and exits the gun barrel.
