The ‘Gömböc’ [‘goemboets] is the first known homogenous object with one stable and one unstable equilibrium point – only two equilibria on a horizontal surface.

It can be proven that no object with less than two equilibria exists.

A series of individual Gömböc models were launched in 2007. Each piece carries a unique number not higher than the current year.

The majority of these Gömböc models are exhibited at famous universities or museums wordlwide.

Gömböc production requires extraordinary precision (0.01 mm).

Thanks to 21st century technology and five years of experiments, Gömböc became available in various sizes, materials and colours.
