During an electrical storm, Martin gets an affliction called popsy, which causes him to appear and disappear uncontrollably. With Tim's help, Martin needs to long ground himself electrically to cure the popsy. Just as he does so, Mrs. Brown drops by and accidentally completes the grounding. In doing so, she gets Martin's levitation power. Martin temporarily fixes the symptom of appearing and disappearing by a concoction of household cleaners. But that is only in a need to get his levitation powers back from Mrs. Brown, which requires an electrically charged transfer. With much maneuvering and wiring and some hand holding (to control Mrs. Brown's levitation, but which she construes as Martin being affectionate with her), Martin manages to do the transfer successfully. After that, Martin and Tim need to try the grounding procedure once again. Just as they are about to do it, Mrs. Brown comes by once again, which Martin and Tim think will cause the transfer of the levitation power all over again. But Mrs. Brown fakes them out - this time, she doesn't cause a problem, and Martin's popsy is finally cured.
