Ibibindi bifunze bidakoreshwa igihe kinini ntibishobora gufungurwa.Impamvu nyamukuru yo kudashobora gufunguraikibindi cya plastikini uko umuvuduko wumwuka wo hanze uruta umuvuduko wimbere.Niba ushaka gufungura umupfundikizo, ugomba kuringaniza umuvuduko wikirere imbere no hanze yikigega.

 
1. Koresha ibyuma bikarishye nibindi bisa, witonze ufungure kuruhande rwicupa ryicupa kugirango umuvuduko wimbere wimbere ninyuma uringanize, hanyuma ufungure;2. Koresha ibyuma bitagira umwanda, ibiyiko bikozwe mu muringa, urufunguzo, gupfunyika impapuro zoherejwe kugirango wongere ubushyamirane, hanyuma Shyira agapira k'icupa ku nkombe z'akanwa k'icupa kugira ngo umwuka winjire mu kabati, hanyuma ukingure;3. Koresha icyuma gityaye cyangwa ibindi bisa kugirango utobore umwobo mu gipfundikizo kugirango urekure umwuka, kandi umuvuduko wumwuka imbere nicupa urashobora gufungura.4. Koresha murugo Icyuma gishyushya umusatsi gishyushya inshuro nyinshi icupa kuva kure kugera hafi, hanyuma urashobora gufungura umuyaga mwinshi;5. Hindura umuyaga urashobora kugera kuri dogere 45, hanyuma ufate umuyaga mwinshi, kanda hepfo yigitereko, umupfundikizo urafungura.Ihame nuguha ikibindi impulse, ikibindi gifunze kirahagarikwa, kandi igice cyumupfundikizo kizakomeza kugenda kubera inertie, kandi icyerekezo nicyerekezo kiri kure yumupfundikizo, bityo kizaba kirekuye.Ku rundi ruhande, kubera ko ikibindi gifunze igihe kirekire, umupfundikizo w’ikibindi gifunze biragoye kuwukuraho kubera imbaraga z’imitsi, kandi gukubita umupfundikizo nabyo bigira ingaruka zo kumena imbaraga za intermolecular;6. Shira ikibindi gifunze mu nkono, hanyuma ukoreshe 80 Shyushya amazi ashyushye mugice cyiminota (menya ko igihe cyo gushyuha kitagomba kuba kirekire), cyangwa urashobora gusuka umupfundikizo namazi ashyushye muminota mike, hanyuma ukuremo umupfundikizo ukomeye kugirango ukingure.
