Hydrogen Bomb Explosion. Here's an entry from the Columbia Encyclopedia:
"Hydrogen bomb or H-bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb."
Certainly we don't need this one... watch the video.
It's beautiful to look at but the consequence is unimaginable.
And here's another video of hydrogen explosion. Again, certainly we don't need to do it too. It is just showing that hydrogen can be produced and that it is indeed a source of energy that can power our cars, our appliances, and with other useful applications.
Be very careful with your hydrogen experiments.
At the end of the day, Making-Hydrogen.com is about how to create hydrogen from solar power to bacteria! What is the coolest way you have discovered in making hydrogen?
