Duke Nukem is overflowing with a radioactive charge, to the point where Captain Planet cannot get near him. However, Captain Planet has an idea to borrow the lead suit from Duke's very own assistant, "Lead Suit". Upon doing so, he is able to block Nukem's radiation with the protection of the suit.
Josie acts like Madam Curie to explain how she discovered radiation and how it works. Beakman talks about how the fission of atoms produces heat, which makes radioactive materials glow. Beakman sets up a demonstration with mousetraps and ping pong balls (atoms) where he hits one and it causes a chain reaction of all of the mouse traps triggering.
