Ua lōʻihi ka nīnau inā ʻoi aku ka maikaʻi o ka ʻaiice cream me ka puna laaua i ʻole he puna metala. Hoʻohana kekahi poʻe i nā puna lāʻau, e like me kā lākou mau mea kīhini punahele, a manaʻo lākou he mau mea hoʻomanaʻo kēia mau mea kuke. Kākoʻo kekahi i nā puna kila kuhiliʻole no ka mea, paʻa a maʻalahi lākou e hoʻomaʻemaʻe. Akā, i ka manawa hea ʻoe e hoʻohana ai i kahi puna lāʻau?

No ka laʻana, maikaʻi ka metalaductility, uila uilaa me ka thermal conductivity, ʻoiai ʻoi aku ka maikaʻi o ka lāʻau i ke kaiapuni a olakino, a ʻaʻole huahaumia plastik.

Ice cream pepa kīʻaha me ka puna lāʻauhoʻohana nui ʻia no ka hoʻopaʻa ʻana a me ka hoʻāʻo ʻana i ka ice cream, a ʻo kona hoʻolālā ʻana i ka laina me ka ʻai ʻana o ka ice cream.
