Magic School Bus Makes a Rainbow

The class finds Ms. Frizzle inside her closet... playing a pinball machine! But it's no ordinary pinball machine - this game is played with light pulses instead of steel balls, and the goal is to use the pulses to light up the six colors of the rainbow! To help Ms. Frizzle win, the kids shrink and go inside the game. With time and the light pulses running out, the kids must discover the secret of what gives things their color - before the principal, Mr. Ruhle, discovers them inside the pinball machine!
