The term 'Badminton Projectile' refers to the shuttlecock, which is a feathered projectile used in the sport of badminton. It is also known as a BIRD or BIRDIE, with the former being a four-letter word and the latter being a six-letter word. The shuttlecock is made up of a round cork base, with 16 feathers attached to it in a conical shape. It is designed to be lightweight and aerodynamic, allowing it to be hit back and forth over the net during a game of badminton.
