Tom qab ntawd, lo lus nug yog, Oobleck hloov ntawm cov khoom mus rau cov kua li cas? Hauv oobleck ua , tus kuj loj khov kho cornstarch molecules tsim cov saw ntev. Cov dej me me ntws dhau los ntawm ib leeg thiab nruab nrab ntawm pob kws molecules tso cai rau cov saw hlau xaub thiab ntws ncig ib leeg. Qhov no yog vim li cas oobleck coj zoo li ib ua kua thaum nws yog tsis nyob rau hauv siab.
Tsis tas li ntawd, Oobleck coj li cas?
Oobleck . Oobleck yog ib qho kev ncua ntawm pob kws thiab dej uas tuaj yeem ua tau coj tus cwj pwm xws li cov khoom lossis cov kua dej nyob ntawm seb koj siv lub siab npaum li cas. Sim tuav qee yam ntawm koj txhais tes, thiab nws yuav tsim ib lub pob khoom hauv koj lub xib teg kom txog thaum koj tso siab. Tom qab ntawd, nws yuav ntws tawm ntawm koj cov ntiv tes.
Oobleck tuaj yeem nres ib lub mos txwv?
Lub cev hnav khaub ncaws siv ua kua rau nres cov mos txwv . Yog tias koj tau muaj sijhawm los ua si nrog qee yam hu ua oobleck , dej uas yog super-saturated nrog cornstarch, ces koj yog ib nrab ntawm kev nkag siab tias cov gel armor ua haujlwm li cas. Thaum xub thawj, oobleck zoo li thiab ua zoo li lwm yam kua.
