Abstract:
1. A blow gun assembly for rapid continuous-firing multiple soft cylindrical projectiles using a single breath, said assembly comprising: a plurality of substantially cylindrical soft projectiles, each of said projectiles having diameter (Dp) and a height (H) and collier radii (R), each said projectile having a central axis centered along said projectile diameter (Dp), a mouthpiece configured to transmit a charge of air in a longitudinally forward direction, a breech, said breech defining a cylindrical internal breech chamber having a circular inner diameter (Db) and a proximal end and a distal end, said proximal end of said breech adjoining said mouthpiece in open fluid communication, said breech chamber having a central axis centered along said breech chamber inner diameter (Db), said breech including a circular projectile entrance port, said projectile entrance port having a diameter substantially equal to said breech chamber inner diameter (Db), a tubular magazine for storing said projectiles in a stacked array, said magazine having an internal diameter (Dm), said magazine having a discharge end in communication with said projectile entrance port of said breech chamber, said magazine configured to feed said projectiles sequentially into said breech chamber with said central axis of each said projectile oriented substantially perpendicular to said central axis of said breech chamber, an elongated barrel extending longitudinally from said distal end of said breech, said barrel having a bore opening in direct communication with said distal end of said breech chamber, an upstream restriction between said mouthpiece and said proximal end of said breech chamber, and a downstream restriction adjacent to said distal end of said breech chamber, and said diameter (Dm) of said magazine being greater than said projectile diameter (Dp) and less than √{square root over ((Dp
