Say goodbye to tedious, time-consuming showers with this “simple, economical and portable sanitary bathing apparatus,” patented in 1913.

Just fill the bag with soapy water, jump in, and pull the drawstring. Now you can hop a bus, eat succotash, even conduct eulogies while attending to your personal hygiene.

Bonus: “By alternate crouching and rising in the bag or by rolling with the same upon a bed or floor on the part of the bather … the liquid in said bag … may be made to surge in simulation of sea waves and thus afford gratification to said bather.”
