Over the next 12 hours, strange things happen. Adam breaks his high chair. Then he cracks the tiled floor. By dawn, he has outgrown his crib. By noon, he punches a hole through the living room ceiling. Wayne realizes with horror: the ray has a delayed, exponential effect. Every time Adam experiences a strong emotion—hunger, excitement, fear—he grows.
The family sits in the ruins of their lab. Sterling Labs’ contract is torn up. Wayne looks at his normal-sized son, who is now drawing on the wall with a permanent marker. Diane sighs. "Honey," she says, "next time, can we just get a babysitter?" honey i blew up the kid
Wayne, bored with commercial success, secretly builds a new device in his garage-lab: a "Gigantic-O-Ray," designed to grow organic matter for world hunger relief. During a hasty experiment while babysitting Adam, Wayne is distracted by a call from Sterling Labs demanding a demonstration. Adam toddles over, grabs the prototype’s antenna, and gets bathed in a brilliant, crackling yellow light. He giggles. Wayne sees no immediate effect. Crisis averted? No. Over the next 12 hours, strange things happen
Wayne’s wife, Diane (Marcia Strassman), is now a real estate agent, exhausted from managing two growing boys. Their eldest, Nick (Robert Oliveri), is a sullen teenager who resents being known as "the kid who got shrunk." Their youngest, Adam, is a curious, mischievous two-year-old with a penchant for putting things in his mouth. By dawn, he has outgrown his crib
As the National Guard prepares to fire on Adam (now 112 feet tall, straddling the Las Vegas Strip), Wayne commandeers the casino’s massive outdoor speaker system. Diane climbs a construction crane to get eye-to-eye with her giant son. Together, they sing the same lullaby Wayne used to sing to Nick when he had nightmares. The sound echoes across the neon desert.
A frantic chase ensues. Adam, now the size of a garage, sees a neon sign for a circus outside Vegas. He thinks it's a giant toy. He waddles toward the Strip, leaving a trail of crushed cars and snapped power lines.
