Objects shaped like 'GÃ¶mbÃ¶c' are impossible to knock over
The 'GÃ¶mbÃ¶c' is the first and only known homogenous object which is known to be impossible to knock over. Pronounced as 'goemboets', the object always finds its way to the same position on a flat surface, no matter how it is placed. It is built with a wide, curved bottom, surrounded by almost-flat sides and a curved ridge on top.
