urine is medicinal

10. Make your race car more durable
In the early 1980s, BMW engineers stored their
Formula 1 engine blocks out in the cold and
peed on them to help harden the metal so that
they could withstand the force of turbocharged
racing.
9. Grow new teeth
As a life support engineer at NASA Ames
Research Center, it’s Michael Flynn’s job to
keep astronauts alive in space, making sure
they have the basic necessities like clean water
to survive. But launching clean water into
space is cost-prohibitive, so for years, Flynn
and his team have been working on new ways
to recycle waste water into safe, drinking
water. SmartPlanet visits Flynn’s lab and looks
at how he’s doing it through a process known
as “forward osmosis.”
8. Soften leather
Roman laundries used large quantities of pee to
bleach fabrics and remove stains. They set
containers around the city, and people relieved
themselves into these. Then, back at the
fullonica, the urine was diluted and dumped
over the clothing as workers stomped on them.
Roman dyers also used urine as a mordant to
seal dyed colors into the fabric. Other cultures
have done the same thing: In the 16th century,
English families had special pots for collecting
urine, that was then exported by the cask-full
to London for dyers there.
7. Sterilize lopped-off body parts
In the 1500s, barber-surgeon Leonardo
Fioravanti saw a man’s nose sliced off during
an argument. He immediately took a leak on
the nose before stitching it back on the poor
fellow who had lost it.
Over the centuries, urine has often been
effectively used to wash battle wounds. While
it’s not completely sterile because of bacteria it
picks up leaving the body, urine is undoubtedly
cleaner than the water that would have been
available in most of those situations.
