This homemade experiment teaches you how to play with hydrogen to be able to pop water bubbles. It just shows us that anyone
can make hydrogen at home. More seriously it raises the question can this hydrogen be used to augment the use of gasoline in a car? VIDEO->
you would be surprised the experiments you can do taking a plug straight from the wall with the end cut off and stuck into the water (without touching each other of course) and adding salt. i wouldn’t recommend doing this if you are not well experienced with electricity… or just stupid.
