Be aware that a cheap way of making fairly pure oxygen is just by heating up manganese
dioxide, which will cause anything that is a like a flame to burn much hotter. I remember
doing an experiment in grade school where you heat up a tablespoonfull of MD in a test
tube with an alcohol burner or (even a match under the tube), then slowly insert a
popsicle stick with a glowing ember (you light the stick with a match then blow it out to
get the glowing ember). The result is that the stick bursts into flame rather violently.
Just saying "BE CAREFUL".
