 * Interesting Notes about Hydrogen:**
 * 1) Hydrogen is the most ABUNDANT element in the universe and often exists as big clouds of gas in space.**
 * 2) The human body is about 11% by MASS. That means that a person that weighs an average of 70kg is made up of 7.7kg of hydrogen alone!**
 * 3) Hydrogen has 3 forms (outside what is required to know) but two of these are used in atomic weapons to make them more destructive. These are called thermonuclear bombs or HYDROGEN BOMBS. These are extremely powerful compared to the first weapons that were used against Japan. **




 * 4) Hydrogen was used in blimps until one blew up becuase it is highly combustable (will ignite quickly). This was known as the Hindenburg disaster. **




 * 5) Liquid Hydrogen is used as rocket fuel (as it is combustable). Often this fuel is mixed with other chemicals to provide an optimum mix to get the highest thrust possible.**
