Sparky Watts #3

Sparky Watts uses one of Doc Static's inventions—a transparent ray that makes things invisible—to play pranks on his friend Slap Happy. When Doc demonstrates the ray at dinner, Sparky becomes concerned that someone might use it for nefarious purposes. Goober, a rival suitor competing for a young woman's affection, sneaks into Doc's house to steal the ray machine, but through a series of mishaps involving the invisibility ray and Sparky's intervention, Sparky manages to thwart Goober's plans. By the story's end, Sparky has won the girl's heart, and Goober's schemes are foiled.
