Guess who's selected to give an exhibition of a slam-dunk during half time of the big basketball game? Phoebe! The problem is Phoebe can't jump high enough. ""If only gravity didn't pull on me!"" she moans. Never one to be tied down, Ms. Frizzle sends the class into space and turns the Bus into a planet — with adjustable gravity! Basketball's a snap with low gravity and a riot with no gravity at all, but when there's way too much gravity, things get really heavy! With Paul Winfield as school principal, Mr. Ruhle.
