If you want to work out your lungs and have fun doing it you might want consider the AirForce BlowGun. Using the power of your lungs the BlowGun can fire a foam dart up to 100 feet, which is 25 feet more than a Nerf N-Strike Elite Rapidstrike CS-18 Blaster. In fact it shoots further than any Nerf gun model we know of. You might surprise yourself the first time you use it. It's also a lot more accurate, and since there are no moving parts, the BlowGun also tend to last longer.
