Science: How does a tree "suck" its water all the way to the top?

This video was made by Veritasium, a Youtuber that does an excellent job creating videos about educational thoughts, ideas, and processes.  In this video he takes you on a journey to find out how a tree can get water all the way to its top when so many other scientific factors and laws support such an impossible possibility.  Veritasium uses friends and scientists to explain how this tree sucking phenomenon is possible.
