High School Chemistry
Testing for hydrogen gas with a burning wooden splint.
Commonly referred to as the pop test.
The hydrogen gas burns with a small explosion, often producing a squeaky pop sound during the process.
Note that the bung was only placed very loosely on the mouth of the tube and did not make an airtight seal, but did trap enough gas for testing successfully.
Portrait orientation for viewing on a smartphone.
The video clip was shot at 240fps, but I don't know if it will play back in slow motion on You Tube.
At 240 fps one can stop frame and see the gas burning with a flame that extends down into the tube.
