Hydrogen gas from water

Hey,

 

I'm wondering what the easiest way of extracting hydrogen gas from water is. I'm guessing it is electrolysis, but could someone give me a detailed explanation of how to do it.

 

Also, is it possible to later use this hydrogen as a propellent for, oh say a potato gun?

Search the chemistry forums, this comes up every other week.
