How can i produce hydrogen in a simple reaction?

Explanation:

Make Hydrogen Gas - Method 1

One of the easiest ways to obtain hydrogen is to get it from water, H2O. This method employs electrolysis, which breaks water into hydrogen and oxygen gas. Unbend the paperclips and connect one to each terminal of the battery.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
