Mukuwedzera, iyo yakaderera viscosity yepende, kana kupenda zvinhu zvinopesana nekuwedzera, kunonoka kuomeswa kwepende kunoburitsa chiitiko chekuyerera.

3. Firimu kuonekwa pinhole

Chikonzero:
1), Chimiro chehuni hachina kukwana zvakakwana, kukuya hakuna kunaka;
2), inokurumidza kusvika kune yechipiri kupfeka isati yatanga kuoma zvachose;
3), isina kuchena zvakakwana, yakaputirwa neguruva, mvura, yakamanikidzwa mweya, mvura, mafuta;
4), mushure mekusanganisa, kwete kumira kwenguva yakakwana;
