A talented youth has compounded a wonderful fluid, a little of which he applies to the mirror in his room, and when he looks into it his image comes to life and comes out of the frame and imitates his every action. As soon as he rubs the fluid off the mirror his double disappears. When the servant come in, a little of the fluid is again rubbed on the mirror, and he has the same experience, his reflection stepping out and doing stunts, thereby scaring the poor fellow almost to death. The inventor of the fluid then takes the mirror with him and goes out on the street.
