Ihe Mere nke 6. Ihe Ndị Ọzọ. Na mgbakwunye na ihe ndị a dị n'elu, enwere ihe ndị ọzọ ga-eme, nke a ga-enyochakwu.
Ngwọta iji gbochie putty mmiri na-eguzogide mmiri ịlaghachi na odo:
Ụzọ nke 1. Jiri ihe mkpuchi azụ maka mkpuchi azụ.
Usoro nke Abụọ. Maka mma mgbidi ochie, a kpụchaala putty nkịtị dị ala nke na-anaghị eguzogide mmiri ma dịkwa mfe ịkpụcha. Tupu e jiri putty dị elu nke na-eguzogide mmiri, a ga-ebu ụzọ mee ọgwụgwọ teknụzụ. Usoro a bụ: buru ụzọ fesa mmiri iji mee ka elu mgbidi ahụ dị mmiri mmiri, ma jiri spatula hichaa ya.
