1. Dib u soo celinta adoo adeegsanaya koobabka nuugista:
Ka dib markii saxanka aluminiumka la gartaa, waxaa lagu soo celin karaa koob cagaar ah. Marka hore, xulo koob cabitaan ah oo cabirkiisa ku habboon, ku rid xarunta dhexe ee aagga qufaca, ka dibna riix gacanta ku jirta xarkaha koobku si adag si aad u qaadatid aagga saafiga ah ee saxanka aluminium ee leh koobka aluminium.
2. Soocelinta ku saleysan mabda'a ballaarinta kuleylka:
Marka lagu daro koobabka nuugista, mabda'a ballaarinta kuleylka waxaa sidoo kale loo isticmaali karaa soo celinta. Tallaabooyinka qaaska ah waa sida soo socota: U adeegso aalad kuleylka si aad ugu kululeyso saxanka aluminium ee dib-u-dhigga ilaa birta ku wareegsan aluminium saxanka aluminium uu leexdo ashen. Ka dib jooji kuleylka oo sug daqiiqado yar. Markan, birta ku wareegsan saxanka aluminium dabiiciga ah wuxuu si dabiici ah u ballaariyaa ballaarinta kuleylka, taasoo u oggolaaneysa meelaha kacsan si tartiib tartiib ah oo si dabiici ah looga soo kabsado.
