leans off to one side, rocks to and fro as if gathering strength and then, presto, tips itself back into a â€œstandingâ€ position as if by magic. It doesnâ€™t have a hidden counterweight inside that helps it perform this trick, like an inflatable punching-bag doll that uses ballast to bob upright after you whack it. No, the Gomboc is something new: the worldâ€™s first self-righting object.
Pretty amazing. Evidently there’s some rather complicated math involved in the Gomboc. Unfortunately though, if you’re interested in owning your own GÃ¶mbÃ¶c, they’re a little expensive. Serial number 17, for instance, is apparently priced at 12, 665 Euros (this price includes a certificate, etc.). So, unless you really want one, you might need to content yourself with an inferior ballast-weighted bag-doll object such as a Weeble or Okiagari-koboshi, both of which, sadly, might just stand on their heads.
