In this video I isolate elemental hydrogen and oxygen and do a few interesting experiments with them
WARNING! This reaction uses CORROSIVE acids, FLAME, HIGH TEMPERATURES, EXPLOSIVE gases, and ecologically harmful MnO2. Do not repeat under any circumstances. I am not responsible for any harm that may come to you should you choose to duplicate this procedure!
Note on MnO2 (manganese dioxide): This compound is toxic to aquatic life and SHOULD NOT BE FLUSHED DOWN THE DRAIN UNDER ANY CIRCUMSTANCES WHATSOEVER!!! Instead, dilute the MnO2 waste from the flask and store it in an appropriate container. You can reuse this in the future to generate more oxygen from H2O2.
