"Chip Switch" is the 12th episode in Season 1 of Lab Rats. It first aired on June 28, 2012.
The Rats switch their bionic chips after talking about how they want a different ability. Adam has Bree's speed, Bree has Chase's intelligence, and Chase has Adam's strength. Ignoring Davenport's warning, they go to school and Chase, not used to heat vision, accidentally traps Leo and Principal Perry inside the elevator during a drill as part of Emergency Preparedness Week at the school after Bree complains about the noise the fire alarm bell makes. Right before Chase traps them, Adam finds out that he has guacamole on his shirt and super speeds home to get tortilla chips for it. Chase is unable to do anything, so the Rats race home try to switch back their chips, but accidentally end up with Chase with Bree's speed, Bree with Adam's strength, and Adam with Chase's intelligence. Adam figures out that Bree can pull the elevator cables, lifting Leo and Principal Perry to safety. This works, but Davenport busts them, but is glad that they learn their lesson about chip switching, and that it didn't cost him a dime.
