For the annual summer science fair, Phineas and Ferb assist Baljeet in constructing a portal to Mars. Candace finds herself vying with another girl for a position at Mr. Slushy Burger. Elsewhere, Doofenshmirtz crafts a bicarbonate volcano for the same event, a further effort to atone for childhood humiliations, during which we glimpse the origin of his signature "-inator" suffix.
