Gatal sangat nak spray tu. Dah benda tu guna untuk spray/cuci keyboard,kau pegi spray tangan. Nasib baik tak frost bite mati urat semua.
Tapi bagus la atleast lepas ni kau tak suka suka spray merata.
HFC-152a ; 1,1-Difluoroethane is a organofluorine compound with the chemical formula C2H4F2. This colorless gas is used as a refrigerant. This gas/liquid evaporates very quickly at standard temperature and pressure, chilling anything in contact with it. This process can produce very cold temperatures, easily sufficient to cause frostbite. Similar cans with dip tubes are marketed as "freeze spray," and will expel liquid when held right side up.
