(Note the bang you hear in the video was not as loud as it was in real life.)
Today I show you how to make hydrogen a easier and safer way. Although it can't fill up a balloon, the bang! you hear when you light it is is enough to surprise yourself.
Edit: When pure Hydrogen is lit on fire it makes a soft pop sound, not a loud bang. The reason why it made a loud bang when I lit is was because there was some oxygen in the mix. I capped the stopper on too quickly and so the Hydrogen wasn't able to "flush" the oxygen from the air out of the flask.
Warning!
Hydrogen produces explosive mixtures in the air. Do not make too much hydrogen at a time and be very careful with flames.
