Honey I Blew Up the Kid (1992)

Three years later, the family of scientist Wayne Salinsky (Rick Moranis Rick Moranis) moved to the coastal community of Nevada to continue his research on electromagnetic molecules. Three years ago, he once "shrunk" the bodies of children because of improper operation, making a series of ironic stories. This time, muddle-headed Wayne still made the same mistake, showing off his own goal. In one experiment, the youngest son Adam, who was only two years old, was "grown up". As long as little Adam is exposed to electric current, his body will keep growing up. The family launched a rescue operation, but it couldn't keep up with the growth of little Adam. In the twinkling of an eye, little Adam had grown into a giant baby measuring 3500 centimeters. To make matters more troublesome, little Adam actually took to the street and headed for Las Vegas, and his wonderful adventure began. Can little Adam shrink back to the size of a normal baby, and can Wayne, a scientist in Oolong, get rid of his embarrassment and be reunited with his family again?
