The news that Niagara Falls may go dry within the next few years has sparked interesting -- and at times, amusing -- Internet debate.
For instance, Randall Munroe, creator of web comic XKCD and author of the book "What If?: Serious Scientific Answers to Absurd Hypothetical Questions," broke down whether Niagara Falls could be consumed through a straw (an alternate means of having the falls go dry, if you will.)
The comic blends practical scientific information with humor -- see an example to the right -- and generally teaches you something.
Do you know what cavitation is? Why do nuclear reactions happen when water collides at such a high speed with the walls of the straw? Isn't this all kind of ridiculous?
I'm not going to spoil whether a pedestrian straw could handle the entire Niagara Falls, but the article is worth a peek if you enjoy physical science or absurd questions.
