Patreon Preview - Detect hydrogen with a carbon monoxide detector (Patreon)

I took in some of your suggestions and rearranged the video for somewhat better flow as well. I think it turned out better.

Looking back, should i address the question of whether the combustible gas sensor also detects carbon monoxide (it does) and why we bother to have to separate sensors? 

(The actual explanation is that having separate indications let's you better assess the dangers of whatever gas is leaking so you can decide whether to evacuate and/or how to find the actual cause (faulty furnace or leaky gas line). I kinda left this out because it was more of a safety procedure question rather than a chemistry question.)

Anyway, i'll post tomorrow if you all approve.
