Zima zikuyandikira.Panthawiyi, anthu ambiri amayamba kugula magalasi.Chifukwa chakuti kutentha kwatsala pang'ono kutsika, madzi otentha otentha amazizira mofulumira.Kumwa madzi ozizira nyengo yozizira ndi koipa kwambiri kwa thupi.Choncho, padzakhala anthu ambiri amene akufuna kusunga madzi awo otentha.Nthawi zambiri, ntchito yabwino yotchinjiriza ndikuwerengera magalasi, koma palinso magalasi ambiri.Ndi mtundu wanji wa galasi wabwino?Momwe mungasankhire Galasi ndi vuto lalikulu kwambiri.
Choyamba tiyenera kuyang'ana kapangidwe ka thermos.Kawirikawiri, mtundu uwu wa thermos umapangidwa ndi chingwe chamkati ndi chingwe chakunja, kotero tiyenera kuwona ngati ziwirizo ziri zofanana.Ngati ali ofanana, ndiye kuti Ubwino ndi wabwino, ngati suli wofanana, mwachitsanzo, pali zovuta zina, ndiye kuti kupanga sikuli kokwanira.
