Adam Szalinski

Adam Szalinski is a character in Disney's 1992 film Honey, I Blew Up the Kid and the 1997 direct-to-video sequel Honey, We Shrunk Ourselves, which were both sequels to the 1989 film. He was portrayed by Daniel and Joshua Shalikar in his first appearance and by Bug Hall in his later appearance.

Background
In the franchise, Adam is the youngest child and second son of Wayne and Diane Szalinski, born during the time skip between the first and second films. In Honey, I Blew Up the Kid, he is a typical 2-year-old toddler, despising naps and often getting into trouble due to his curiosity. Much of the film's struggle comes from the fact that he only registers his parents when they are bigger than he is. In Honey, We Shrunk Ourselves, he is at around ten. Unlike Nick, who shared his father's scientific interest, he prefers baseball to science, though he initially doesn't know how to explain this to his father.

Honey, I Blew Up the Kid
When Diane takes their oldest daughter, Amy, to college, Wayne is charged with watching Adam and Nick. On Saturday, he takes them to the lab where he works, in an attempt to get one last test run of his latest invention, a machine that enlarges matter. During the test, Adam unknowingly escapes from his stroller, and wanders into the machine's path. While nothing seems to happen at first, it is later seen that he grows when in close contact with the electromagnetic energy given off by electric-powered devices.

Though Wayne first attempts to return Adam to the lab to reverse the process, the presence of a coworker, Dr. Charles Hendrickson, who had been trying to take over Wayne's project, forces them to return home. By this time, Diane has returned, and is shocked to see that Adam is now over seven feet tall. While Wayne and Diane return to the lab to get Wayne's shrinking machine, Adam grows again to 14 feet tall while watching TV, forcing Nick and Mandy Park, his babysitter, to try to find him. All three are captured by Dr. Hendrickson, who reported them to the head of the labs, Clifford Sterling, and engaged law enforcement to track Adam down.

Adam grows again, this time due to being near electric wires, and escapes from the truck carrying him, picks up Nick and Mandy, puts them in his pocket, and takes them with him. He eventually ends up in Las Vegas, where he wanders around the Strip, thinking it's a playground. By this time, Wayne and Diane have come to town with the machine, assisted by Sterling, who has fired Dr. Hendrickson and offered the parents his support. An initial attempt to make Adam stay still by lulling him to sleep fails. After this, Dr. Hendrickson, angry at his firing, attempts to shoot Adam with tranquilizers. Luckily for him, Diane appears, temporarily enlarged due to the machine, and holds him, keeping him still long enough for Wayne to shrink them both, returning Adam to normal size.

Honey, We Shrunk Ourselves
Adam, now ten, has developed a love for baseball in contrast to his father's and brother's love of science and invention. However, Wayne desires to send him to science camp, and Adam had trouble making him understand his preferences.

When Diane and Aunt Patti prepare to travel on a vacation, Adam is meant to stay at home with his father, Uncle Gordon, and two cousins. When he and his cousins are sent to buy groceries, Wayne and Gordon accidentally shrink themselves while secretly trying to shrink a Tiki Man ornament Diane wants to throw out. When Diane and Patti return to drop off medicine for Adam's cousin Mitch, they are also shrunk. When Adam and his cousins return home, they believe Diane and Patti to be on vacation. Meanwhile an undeleted voicemail message leads them to believe that Wayne and Gordon have left unexpectedly to see a shuttle launch. While the adults try to get their kids' attention, they, thinking they have the house to themselves, invite friends over for a party.

During the adults' attempts, Wayne overhears Adam's desire to go to baseball camp rather than science camp, and comes to understand his interests better. Later on, Mitch becomes ill due to a potassium deficiency (he was unable to find the medicine his mother left for him). Adam is able to save him when he remembers Wayne telling him that bananas had potassium. When the adults finally get theirs kids' attention, Adam and his cousins are able to ready the machine thanks to Wayne's instructions. They briefly contemplate leaving their parents shrunk after Adam mentions the idea, but decide against it. After being returned to normal size Wayne offers to send Adam to baseball camp and apologizes for not realizing that he had different interests.
