Honey, I Blew Up the Kid (1992)

Wayne Szalinski is at it again. But instead of shrinking things, he tries to make a machine that can make them grow. As in the first one, it isn't quite accurate. But when he brings his sons, Nick and Adam, to see it, it starts working unexpectedly. And when Adam comes right up to it, he gets zapped along with his stuffed bunny. Now, whenever he comes near anything electrical, it causes him to grow. He soon reaches a height of 112 feet. And he is now walking through Las Vegas which he thinks is one big playland.
