Good news: We now have a easy way to explain space travel and the science of rockets -- sorry, up-goers -- that should make sense to everyone.
"The best way we know of to get to space and stay there is an up-goer that burns fire water, usually made from old dead animals or the kind of air that once burned a big sky bag and people died."
See? Simple.
The space travel lesson was created by the popular YouTube channel Minute Physics to help promote xkcd creator Randall Munroe's new book, Thing Explainer: Complicated Stuff in Simple Words.
Throughout the book, Munroe uses only the 1,000 most common words in the English language to explain complex ideas -- hence this video, which hiliariously manages to steer clear of such complex words as "rocket" and "orbit."
