Nigel Baldwin | Oxygen gas test with a glowing splint WZNEE5015 @nigelbaldwin3184 | Uploaded February 2022 | Updated October 2024, 5 minutes ago.
High School Chemistry
Hydrogen peroxide and dried yeast were used to generate oxygen gas. However, the rate of production of gas was too slow, so a little potassium iodide was added to the mixture and oxygen gas was produced far quicker.
The beaker got very hot and big bubbles of gas were produced.
A glowing splint was introduced near the top of the beaker near the bursting bubbles.

The movie clip was shot in portrait mode for viewing on a smartphone. I hope that You Tube doesn't autocorrect the orientation.
