Amaqiniso athakazelisayo ngokuhola Yithuba elihle lokufunda kabanzi ngezinsimbi. Njengoba insimbi inobuthi, akufanele isetshenziswe empilweni yansuku zonke, ngaphandle kwalokho, ngokuhamba kwesikhathi, ingadala ubuthi obukhulu.
Ngakho-ke, nanka amaqiniso athakazelisa kakhulu ngokuhola.
- Umthofu wayethandwa kakhulu ngabantu basendulo, njengoba kufakazelwa ukutholwa kwezinto eziningi zakudala. Ngakho-ke, ososayensi bakwazi ukuthola ubuhlalu bokuhola obudala babo budlula iminyaka eyizinkulungwane eziyisithupha.
- EGibhithe lasendulo, ama-statuette nezindondo zenziwa ngomthofu, manje ezigcinwa kumamnyuziyamu ahlukahlukene emhlabeni jikelele.
- Ebukhoneni be-oxygen, lead, njenge-aluminium (bona amaqiniso athakazelisayo nge-aluminium), i-oxidize ngokushesha, imbozwe ifilimu elimpunga.
- Ngesinye isikhathi, iRoma lasendulo lalihola umhlaba ekukhiqizeni umthofu - amathani angama-80,000 ngonyaka.
- AmaRoma asendulo enza amapayipi amanzi ngomthofu enganakile ukuthi ayenobuthi obungakanani.
- Kuyathakazelisa ukuthi umqambi wezakhiwo ongumRoma nomakhenikha uVetruvius, owayephila ngisho nangaphambi kwenkathi yethu, wamemezela ukuthi ukuhola kwaba nomthelela omubi emzimbeni womuntu.

- Emzimbeni wethu, umthofu uhlangana nezicubu zethambo, kancane kancane kususa i-calcium. Ngokuhamba kwesikhathi, lokhu kuholela emiphumeleni emibi.
- Ummese obukhali osezingeni eliphezulu ungasika kalula ingot yomthofu.
- Namuhla, iningi lokuhola lingena ekukhiqizeni ibhethri.
- Ukuhola kuyingozi ikakhulukazi emzimbeni wengane, ngoba ukufaka ubuthi ngensimbi enjalo kuvimbela ukukhula kwengane.
- Izazi ze-alchemist zeNkathi Ephakathi ezihambisana nokuhola noSaturn.
- Kuzo zonke izinto ezaziwayo, ukuhola ukuvikela okuhle kakhulu emisebeni (bona amaqiniso athakazelisayo ngemisebe).
- Kuze kube ngama-70s wekhulu elidlule, izithasiselo eziholayo zengezwe kuphethiloli ukwandisa isibalo se-octane. Kamuva, lo mkhuba wanqanyulwa ngenxa yokulimala okukhulu okwabangelwa imvelo.
- Ucwaningo lwakamuva lukhombisile ukuthi ezifundeni ezinesilinganiso esiphansi sokungcoliswa komthofu, ubugebengu buvela kaningi kakhulu kunasezifundeni ezinomthamo omkhulu womthofu. Kuneziphakamiso eziholayo ezinomphumela omubi ngokweqile ebuchosheni.
- Ubuwazi ukuthi awekho amagesi ancibilika kumthofu, noma ngabe usesimweni soketshezi?
- Enhlabathini, amanzi nomoya wedolobha elikhulu, okuqukethwe okuholayo kuphakeme izikhathi ezingama-25-50 kunezindawo zasemakhaya lapho kungekho mabhizinisi khona.
