Curious Minds Metal Flip Over Tippe Top in Drawstring Pouch (single)
Discover the fascinating world of physics with the Curious Minds Metal Flip Over Tippe Top.
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.
Furthermore, if it is originally spun in the direction of an arrow painted upon its hemispherical portion, upon flipping, it spins opposite the direction of the arrow.
Flip over tops (often known as a The Tippe Top) were originally invented in 1950 by the Danish engineer Werner Østberg. 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 some credit should be given to Helene Sperl who in 1891 patented a Wendekreisel in Germany. However the patent ran out and it was never mass produced.
The tops are 29mm in diameter ( 1. 14 inches ) and about 36mm tall (1. 41 inches ).
