10 x Metal Flip Over Tops

These highly polished solid metal flip over tops 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.

Flip over tops (often known as tippie tops) were originally invented in 1950 by the Danish engineer Werner Ostberg. His inspiration came 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 credit should be given to Helene Sperl who in 1891 patented a "Wendekreisel" in Germany. The patent ran out and it was never mass produced.
