Electrolysis of Water

Pierce and I successfully extracted hydrogen and oxygen from water although, to our disappointment, we we did not manage to get enough hydrogen for a satisfying puff of flame. As usual, Pierce embellishes my instructional diagrams. The video is rather long owing the in-depth explanation of the processes taking place, the time taken to embellish diagrams, and the fact that one of our electrodes broke about half-way through the experiment which went undetected for a while.

If you want to see some highlights:

2:50 the water molecule

12:10 the equipment

19:15 applying power

27:20 how salt dissolves

42:30 discovering the broken electrode

50:20 no explosion :-(
