The sixth and final book in the New York Times bestselling series that's full of funny jokes, clever science experiments, and robot hijinks. “I never thought science could be funny . . . until I read Frank Einstein. It will have kids laughing.” —Jeff Kinney, Diary of a Wimpy Kid

In Frank Einstein and the Space-Time Zipper, Frank Einstein (kid genius, scientist, and inventor) and his best friend, Watson, along with Klink (a self-assembled artificial-intelligence entity) and Klank (a mostly self-assembled and artificial-almost-intelligence entity), once again find themselves in competition with T. Edison, their classmate and archrival—this time studying the science and mysteries of the universe!
