- Ncuav lub lim sib tov rau hauv enameled ntim, muab on qhov hluav taws kub thiab nyob rau ntawm thawj kos npe ntawm boiling, stirring maj mam, ncuav nyob rau hauv 95 g ntawm ammonium nitrate. Tseem stirring, boil rau peb feeb, ces tshem tawm los ntawm tshav kub thiab cia txias.
- Ncuav sov tov rau hauv lub raj mis yas thiab cia kom txias. Thaum cov kua kub txias lawm, muab tso rau hauv lub fridge rau ib teev, tom qab lub sijhawm dhau los, hloov mus rau lub tub yees, tuav nws rau peb teev.
- Tom qab tag nrho cov txheej txheem txias, tshem tawm lub raj mis thiab ua tib zoo ntws dej: potassium nitrate yuav nyob twj ywm nyob rau hauv daim ntawv ntawm iav ci nyob rau hauv qab. Qhuav cov nplais ntawm daim ntawv nyob rau hauv ib qho chaw qhuav thiab sov so rau ob peb hnub. Ntsev yog npaj txhij.
