   This reminds me of when as a child I was creating hydrogen from HCl and Al or Mg. It ended with a small hole in my rooms ceiling, as one time when I lighted the hydrogen the metal tube on top of the test-tube flew off like a rocket.

   But it was a good experiment to show the potential of hydrogen as a future fuel source. If I remember correctly, while same amount of hydrogen actually has 3 times less energy than gasoline, it weighs 10 times less.

   Nowadays it is probably much more fun to experiment with fuel cell kits.

   Magnesium and Potassium are just good fun, especially in the bathtub

   Does it truly take 50% more energy to electrolize hydrogen than you get out of the hydrogen? That seems like the bummer of the process. Losing 50% of your energy off the top before you even reclaim it on the other end seems troublesome…
