Stuntmen Perform Mind Blowing Bow And Arrow Acrobatic Trick Shots

A bow is a flexible arc which shoots aerodynamic projectiles called arrows. A string joins the two ends of the bow and when the string is drawn back, the ends of the bow are flexed. When the string is released, the potential energy of the flexed stick is transformed into the velocity of the arrow.[1] Archery is the art or sport of shooting arrows from bows.[2] Today, bows and arrows are used primarily for hunting and for the sport of archery. Though they are still occasionally used as weapons of war, the development of gunpowder and muskets, and the growing size of armies, led to their replacement in warfare several centuries ago in much of the world. Someone who makes bows is known as a bowyer,[3] and one who makes arrows is a fletcher[4] —or in the case of the manufacture of metal arrow heads, an arrow smith.[5]
Scythians shooting with bows, Panticapeum (known today as Kertch, Ukraine), 4th century BCE. The bow and arrow was not the first composite projectile weapon to be invented. It was preceded by the sling and by spear throwers such as the atlatl of the Americas and the woomera of Australia. A number of cultures in historical times lacked the bow and arrow, and in others oral history records a time before its acquisition. The earliest potential arrow heads date from about 64,000 years ago in the South African Sibudu Cave.[6][7] By 16,000 BCE flint points were being bound by sinews to split shafts. Fletching was being practiced, with feathers glued and bound to shafts.[citation needed] The first actual bow fragments are the Stellmoor bows from northern Germany.[8] They were dated to about 8,000 BCE but were destroyed in Hamburg during the Second World War, before carbon 14 dating was available; their age is attributed by archaeological association. The oldest bows in one piece are the elm Holmegaard bows from Denmark which were dated to 9,000 BCE. High performance wooden bows are currently made following the Holmegaard design. The bow and arrow are still used in tribal warfare in Africa to this day. An example was documented in 2009 in Kenya when the Kisii-tribe and Kalenjin-tribe clashed resulting in four deaths.[9][10]
