Just came across this channel... You guys do an awesome job for a couple of kids. Very well put together presentation. Hope you got good marks. (Yeah, I know it was a couple years ago...)
so.... the balloon i filled with gas... was oxygen and hydrogen gas? i used sodium/potassium hydroxide (drain opener) and aluminium foil in a bottle.. or was it just hydrogen? or... did the air from the bottle mix with the hydrogen .. ?
(Not that this is relevant to this video,) but sodium hydroxide and aluminum makes only hydrogen gas and sodium aluminate. when the balloon is ignited, it reacts with oxygen gas in the air.
it could have mixed with oxygen from the bottle, and when the hydrogen flowed into the balloon it pushed oxygen gas from the free space inside the bottle as well, with both of them ending up in the balloon.
