Kubadwa kwa kapu ya korona

Zipewa za korona ndi mtundu wa zipewa zomwe zimagwiritsidwa ntchito masiku ano mowa, zakumwa zozizilitsa kukhosi ndi zokometsera. Ogula amasiku ano adazolowera kapu ya botololi, koma ndi anthu ochepa omwe amadziwa kuti pali nkhani yaying'ono yosangalatsa yokhudza kupangidwa kwa kapu ya botololi.
Painter ndi makanika ku United States. Tsiku lina, Painter atabwera kuchokera kuntchito, anali wotopa komanso ali ndi ludzu, choncho anatola botolo la madzi a soda. Atangotsegula kapuyo, anamva fungo lachilendo, ndipo m’mphepete mwa botololo munali choyera. Sodayo inali itaipa chifukwa inali yotentha kwambiri komanso kapu inali yotayirira.
Kuphatikiza pa kukhumudwitsidwa, izi zidalimbikitsanso majini aamuna a Painter's science and engineering. Kodi mungapange chipewa cha botolo chosindikizidwa bwino komanso chowoneka bwino? Ankaganiza kuti ma botolo ambiri panthawiyo anali opangidwa ndi zomangira, zomwe sizinali zovuta kupanga, komanso zosatsekedwa mwamphamvu, ndipo zakumwazo zinkawonongeka mosavuta. Choncho anatolera matumba a mabotolo pafupifupi 3,000 kuti aphunzire. Ngakhale kapu ndi chinthu chaching'ono, ndizovuta kupanga. Wojambula, yemwe sanadziwepo za zipewa za botolo, ali ndi cholinga chomveka, koma sanabwere ndi lingaliro labwino kwa kanthawi.
Tsiku lina, mkaziyo anapeza Painter ali wopsinjika maganizo kwambiri, ndipo anamuuza kuti: “Usade nkhawa, wokondedwa, ukhoza kuyesa kupanga kapu ya botolo ngati korona, ndiyeno nkuipopera!”
Atamvetsera mawu a mkazi wake, Painter anaoneka kuti ali ndi mantha: “Eya! Chifukwa chiyani sindinaganizire zimenezo?” Nthawi yomweyo adapeza kapu yabotolo, kupindika mozungulira kapu yabotolo, ndipo adapanga kapu yabotolo yowoneka ngati korona. Kenako ikani kapu pakamwa pa botolo, ndipo potsiriza akanikizire mwamphamvu. Pambuyo poyesedwa, zidapezeka kuti kapuyo inali yolimba ndipo chisindikizocho chinali chabwino kwambiri kuposa chipewa cham'mbuyomu.
Chophimba cha botolo chomwe chinapangidwa ndi Painter chinapangidwa mwamsanga ndipo chimagwiritsidwa ntchito kwambiri, ndipo mpaka lero, "zisoti za korona" zidakali paliponse m'miyoyo yathu.
