Sosanping Metal Flip Over Top (Tippie Top) by Gyroscope.com

These are highly polished solid metal flip over tops. They have a chrome like finish and are excellently machined. Simply spin it as normal and watch it suddenly flip over and then continue to spin upside-down. These flip over tops (often known as a The Tipped Top) were originally invented in 1950 by the Danish engineer Werner Oostburg. His inspiration can from a visit to South America where he had seen local people playing with a small, round fruit. When they turned it by the stalk like an old-fashioned spinning top, it would spin for a second and then invert and spin on the stalk. However some credit should be given to Helene Sperm who in 1891 patented a Wendekreisel in Germany. However the patent ran out and it was never mass produced. These tops are made from polished aluminum and are 29mm in diameter.
