Izimbiza ezivaliwe ezingakaze zisetshenziswe isikhathi eside ngokuvamile azikwazi ukuvulwa.Isizathu esiyinhloko sokungakwazi ukuvula i-imbiza yepulasitikiukuthi umfutho womoya wangaphandle uphakeme kunomfutho womoya wangaphakathi.Uma ufuna ukuvula isivalo, kufanele ulinganise ukucindezela komkhathi ngaphakathi nangaphandle kwethangi lokugcina.

 
1. Sebenzisa imimese ebukhali nokunye okunjalo, vula ngobumnene onqenqemeni lwesivalo sebhodlela ukuze ugcine ingcindezi yomoya yangaphakathi nengaphandle ilinganisela, bese uvula;2. Sebenzisa insimbi engagqwali, izinkezo zethusi, izihluthulelo, amathawula ephepha lokugoqa ukuze ukhulise ukungqubuzana, bese u-Pry ikepisi yebhodlela emaphethelweni omlomo webhodlela ukuze umoya ungene ethini, bese ulivula;3. Sebenzisa ummese obukhali noma okufana nalokhu ukuze ubhoboze imbobo esivalweni ukuze uvule umoya, futhi umfutho womoya ngaphakathi nangaphandle kwebhodlela ungavuleka.4. Sebenzisa ekhaya Isomisi sezinwele esishisayo sishisa ngokuphindaphindiwe i-cap yebhodlela ukusuka kude kuya eduze, futhi ekugcineni ungakwazi ukuvula ithini elingangeni umoya;5. Guqula ithini elingangeni moya libe i-engeli engama-degree angu-45, bese ubamba ithini elingangeni, uthephe phansi kwekani, futhi isivalo sizovuleka.Umgomo ukunikeza imbiza umfutho, imbiza evaliwe ivaliwe, futhi ingxenye yesivalo izoqhubeka nokunyakaza ngenxa ye-inertia, futhi isiqondiso siyisiqondiso esivela kude nesivalo, ngakho-ke sizokhululeka.Ngakolunye uhlangothi, ngenxa yokuthi imbiza ivalwe isikhathi eside, isivalo sembiza evaliwe kunzima ukususa ngenxa yamandla e-intermolecular, futhi ukushaya isivalo nakho kunomphumela wokuphula amandla e-intermolecular;6. Gcoba imbiza evalwe ebhodweni, bese usebenzisa i-80 Yishise ngamanzi ashisayo isigamu somzuzu (qaphela ukuthi isikhathi sokushisa akufanele sibe side kakhulu), noma ungathela isivalo ngamanzi ashisayo imizuzu embalwa; bese udonsa isivalo ngamandla ukuze usivule.
