TIME TO RELAX
In the 19th century, water therapy was a popular
treatment for all sorts of ailments and this US patent,
registered in 1900 by Otto Hensel, shows his rocking
bathtub, which moved up and down to gently splash
water against the bather. A curtain from the tub to
the bather’s neck kept the water from spilling. Today,
people may relax in hot tubs, whirlpool baths, and
showers with varying jets of water. AT HOME
