Dr. Hathaway (William Atherton) had used the students to create the laser as a destructive government weapon, which makes the students none too happy. Chris (Val Kilmer), Mitch (Gabriel Jarret), Jordan (Michelle Meyrink), and Lazlo (Jon Gries) successfully reprogram the target of the weapon's destructive beam to hit Hathaway's new home. The laser heats up the huge amount of popcorn the students placed in Hathaway's house, which basically creates a giant Jiffy Pop explosion. The popcorn fills the entire house -- a house which Hathaway purchased using some of the grant money from the government -- and makes the house break apart, humiliating Hathaway in the process.
