On August 03, 2012, Thursday Google is featuring "Shot Put" by showing the Doodle "London 2012 shot put". This is the Eighth Google Doodle for the London 2012 Summer Olympics. "Shot Put" event is taking place from Friday 3 August, 2012 -- Sunday 12 August, 2012. "Shot Put" is a track and field event involving "putting" a heavy metal ball—the shot—as far as possible.It is common to use the term "shot put" to refer to both the shot itself and to the putting action. In open competitions the men's shot weighs 7.260 kilograms (16.01 lb), and the women's shot weighs 4 kilograms (8.8 lb). The three styles of shot put is as follows: 1. Disco-put 2. Parry O'Brien 3. Orthodox. But two new putting styles are in current general use by shot put competitors: the glide and the spin. glide: The origin of the glide dates to 1951, when Parry O'Brien of the United States invented a technique that involved the putter facing backwards, rotating 180 degrees across the circle, and then tossing the shot. spin: The spin may have been independently invented in the United States Which was invented by coach Viktor Alexeyev.The spin involves rotating like a discus thrower and using rotational momentum for power. The shot put ball is made of different kinds of materials depending on its intended use. Materials used include iron, cast iron, solid steel, stainless steel, brass, and synthetic materials like polyvinyl. Some metals are more dense than others making the size of the shot vary, for example, indoor shots are larger than outdoor shots, so different materials are used to make them.
