Birth of the Atom!
When scientist Ray Palmer finds a dwarf star fragment, he creates lenses out of it to create a shrinking device. However, all of his tests finds that every object he shrinks with the lenses explodes after an hours work.
One day while taking out his fiance Jean Loring and an hiking club to a cave, they get trapped in an avalanche. Going on his own to find a way out, Ray decides to use his lenses to shrink himself down to size to climb up to an opening and make it larger, using an engagement ring he has for Jean.
After succeeding in making an opening, Ray returns to his original size, and believes that he survived the experience when drippings from the cave landed on the lenses. However, after everyone is safe, Ray still finds that his lenses still cause items to explode after an hour, leaving Ray to realize that perhaps something in his own body prevents him from being destroyed when staying at a small size for an extended period of time.
