1. A blow gun to fire spherical projectiles, each spherical projectile defining a spherical projectile diameter, the blow gun consisting of: a hollow ammunition chamber having an internal volume that is large enough to hold at least 30 of the spherical projectiles, the ammunition chamber having an ammunition refill aperture; a barrel obtruding from the hollow ammunition chamber, the barrel having a cylindrical bore therethrough, the cylindrical bore defining an internal diameter that is greater than the spherical projectile diameter but no greater than 1.7 times the spherical projectile diameter; and a lid over the ammunition refill aperture; wherein the hollow ammunition chamber has a breath receiving orifice for receiving exhaled breath into the hollow ammunition chamber thereby disturbing the spherical projectiles within the hollow ammunition chamber before the spherical projectiles enter the barrel; and wherein the ammunition chamber has a firing port and the barrel obtrudes from the hollow ammunition chamber through the firing port, and the barrel has an outer surface that is in sliding contact with the firing port, and the barrel has a storage position in which most of the barrel is disposed within the internal volume of the hollow ammunition chamber, and the barrel has a firing position in which most of the barrel is disposed outside of the hollow ammunition chamber.
