We can create Oxygen at home. Just take hydrogen peroxide (available in any medical store) and take MnO2(available in any dry cell i.e. remove carbon rode and remaining black substance is MnO2) take in 1:8 ratio or as you wish but take MnO2 in small amount . The reaction takes place and the displaced gas is O2 .. (Plz do reaction in a container and carefully)
