Hypergolic

On my path to wild success on the GRE's sometime in the future; I bring hypergolic. It means igniting on contact. This means it does not need a spark to ignite. I can not think of an example of something that is hypergolic but it seems like an interesting word to know. Oh, heres one a very few people will know but is good; Will Hoff has a tendency to be hypergolic. For some reason blogger thinks hypergolic is spelled wrong.
