Phezulu okubuyela umva, iLitye leCelt

Ubungakanani 9.6x2x1cm, Ukupakisha i-16.5x9x1cm, i-PVCA i-rattleback, ekwabizwa ngokuba yi

Umphezulu wokujikeleza, okwaziwa ngokuba lilitye leCeltic, ungaphezulu kwe-elliptical. Iya kujikeleza kwicala elithile; Nangona kunjalo, xa ijikwe kwicala elichaseneyo, iya kuzinza, inyikime, ime, kwaye emva koko itshintshe ijikeleze kwicala langasentla.
Lo mjikelo wokujikeleza ujikeleza ubonakala ngathi wophula umthetho wolondolozo lwe-angular umfutho kwi-physics. Eyona nto imangalisayo kukuba xa sijika i-gyroscope yaya kwicala elithile, uninzi lwee-gyroscopes alunakuba nalo mcimbi ukhethekileyo; kuyakwenzeka kwelinye icala. Ezi mpawu zimbini zenza ukuba ukujikeleza okuphezulu kube yinto enqabileyo, ethe yavuselela umbono wabantu abaninzi ukusukela kumaxesha angaphambi kokubhalwa kwembali.
