Weather Waterloo - S1.E12

Billy is the only student who didn't make his own Earth Science project to be judged in class. He put off building the ""weather nullifier"" that he designed, using the time to play baseball and watch TV instead. With no time left to make the project, Billy ends up having to buy one. Before the judging takes place, Earl submits his own project, a ""preter atmospheric generator"" that he believes will win. When it doesn't, Earl angrily turns it on, unleashing a tornado, a mudslide and a thunderstorm on the school! When Billy's nullifier fails to work, he finally builds the one that he was supposed to for class. Only then is Earl's weather attack stopped, and a lesson in the perils of procrastination learned.
