In science we used fire to test for the gases produced when you put metals in acids and bases .

The first test was for hydrogen using the pop test, a burning splint inserted into a test tube full of hydrogen to produce a pop sound. By adding a strip of magnesium to a test tube containing acid and holding a bigger boiling tube over top you can collect hydrogen to pop.

The second test was for oxygen, adding magnesium dioxide to hydrogen peroxide, a base, created oxygen. The oxygen was tested for by placing a recently blown out splint in the test tube to see if it would relight.

The third and final test was for carbon dioxide, Adding together an acid and a metal carbonate will produce carbon dioxide, which can be tested by inserting a burning splint. If the splint goes out you have carbon dioxide, it smothers flames.
