Movies - Honey, I Shrunk the Kids

Honey, I Shrunk the Kids is a 1989 comedy film. Having problems at home with his wife Diane, struggling inventor Wayne Szalinski has created an electro-magnetic shrink ray - unfortunately it only seems to make things explode. While at work, his neighbor's son, Ron Thompson, hits a baseball into the Szalinskis' attic window and starts the shrink ray. Ron and his older brother Russel and Wayne's children, Amy and Nick, go up to the attic to retrieve the baseball. Luckily, the baseball gets stuck in the machine and blocks one of the laser components, resulting in it only releasing enough energy to shrink things instead of blowing them up, and the kids and a nearby couch are shrunk by the beam when it fires.
