Equilibrium: Sensational Hungarian Invention “Gömböc” To Hit The Stores Next Year

By Tamás Székely // 2016.07.20.

The serial production of Gömböc, a unqiue Hungarian invention, will start soon, Hungarian news portals, including, reported. The invention of the Gömböc has been in the focus of public and media attention, repeating the success of another Hungarian Ernő Rubik when he designed his legendary cube-shaped puzzle in 1974.


Gömböc is a convex three-dimensional homogeneous body which, when resting on a flat surface, has just one stable and one unstable point of equilibrium. Its existence was conjectured by Russian mathematician Vladimir Arnold in 1995 and proven in 2006 by Hungarian scientists Gábor Domokos and Péter Várkonyi. It is possible to purchase a limited edition of Gömböc even today, but it costs 199 euros due to its expensive material that includes aluminium alloy, brass, plexiglass and marble.

According to the latest reports, however, a new Gömböc will hit the stores soon in Hungary, made of a special plastic material this time. It will cost 10.000 Hungarian forints (about 32 euros) but it is expected to decrease to half of that price after a while. Although in theory the balancing properties should not depend on the material and object size, in practice, both larger and heavier Gömböcs have better chances to return to equilibrium in case of defects.
