Voiceover
Now oxygen is added to the gas stream, but the oxygen is flowing more slowly than the hydrogen. Again soap bubbles are formed, float upward and are ignited. The bubbles explode more loudly. The hydrogen plus oxygen reaction is occurring more rapidly, because there's oxygen within the soap bubble in addition to the oxygen available in air.
