Umshini wami weVan De Graaff ukhiqiza ugesi omile.Asikho ngempela isipoki emshinini wami, kodwa ugesi omile okhiqizwayo ukhiqiza ama-electron amaningi.Kufana kakhulu nokuhamba kukhaphethi ogqoke amasokisi ewuli.Lawo ma-electron agelezela emathini kaphaya wami.Njengoba wonke amathini kaphaya eshajwa ngokufanayo, ayahlukana, njengoba izinto eziphikisanayo ziheha futhi ziyaxosha, ngakho zindizela kuso sonke isitudiyo.
Ngezakho izipoki, uzodala ukushajwa okungekuhle entweni yepayipi le-PVC kanye nokushajwa okungekuhle kwendandatho evela esikhwameni somkhiqizo.Ngoba zombili zizoba necala elibi, zizophusha zihlukane futhi ungenza indandatho yakho yesipoki intante!
Ngingakwazi ukulawula leli bhodlela ngengqondo yami... ungakwazi?Mhlawumbe kukhona isipoki ebhodleleni esidala ukuthi lehle lenyuka??Cha!Lokhu kubizwa ngokuthi i-cartesian diver.Uma ucindezela izinhlangothi zebhodlela, ukhulisa ukucindezela oketshezini ngaphakathi.Lokho kusho ukuthi nawe ukhulisa ingcindezi ku-eyedropper uqobo.
Uma ucindezela ngokwanele futhi uzophusha amanzi engeziwe phezulu ngaphakathi kwe-dropper.Umoya ongaphakathi kwe-dropper uyacindezela kakhulu njengoba amanzi ephoqelelwa ukuba angene. Uma ucindezela amanzi amaningi ngaphakathi kwe-dropper, unyusa ukuminyana kwawo kukonke.
Uma ukuminyana kwayo sekungaphezu kwalokho okuzungezile, izocwila.Khipha ukucindezela ezinhlangothini zebhodlela bese uyeka ukuphoqa amanzi ngaphakathi kwe-eyedropper.Umoya ongaphakathi kuyo manje uzophusha amanzi engeziwe futhi futhi i-eyedropper izokhuphuka.Ungenza i-diver ngephakethe le-ketchup, i-eyedropper noma ngisho notshani nobumba.Vele uyihlole kuqala ukuze uqiniseke ukuthi ayintanti kancane emanzini ngaphambi kokuthi uyinamathisele ebhodleleni.
Ukuze wenze i-Monster Spit udinga inkomishi engu-1 kaviniga omhlophe kanye nensipho yesitsha ye-TBSP engu-1.Hlanganisa kahle bese wengeza umbala wokudla uma uthanda.
Ukwenza izipoki ze-barfing, thatha ibhodlela le-creamer elingenalutho bese udweba ebusweni.Sika imbobo encane emlonyeni.Faka cishe 1/4 inkomishi yokubhaka soda ebhodleleni.Engeza mayelana ne-1/2 indebe ye-Monster Spit futhi isipoki sizokhipha.Amabhamuza abamba i-carbon dioxide ekhishwa lapho uviniga ne-baking soda kuxutshwa.
