  1. History of the Toilet By: Diego Davila

  2. Going inside • About 2500 BC, the city dwellers of the Indus Valley built the earliest known indoor toilets. • -The toilets emptied into a brick-lined sewer system. • This plumbing technology is lost to the region when the cities are invaded around 1500 BC.

  3. Royal Flush • About 1500 bc: Plumbers on the Greek island of Crete install the world's first flush toilet in the queen's bathroom. • When the queen flushes, a tankful of rainwater is released into the bowl and washes her doings down clay pipes that run through the palace. • Around 1400 AC an earthquake destroyed the royal palace.

  4. Really Public Bathrooms • About 800 bcin Rome, construction of the Cloaca Maxima takes place. • It's an enormous sewer system that carries the city's waste to the Tiber River • As many as 11,000 seats are lined up in rectangular rooms with no privacy. • For wiping, there's a sponge on the end of a stick.

  5. This Job is the Pits • In 1300 AD many Europeans are doing their business in outhouses • Richard the Raker meets an unpleasant end: While cleaning out the waste under his own outhouse, he falls through the floor and drowns in his own excrement.

  6. Heads Up • In the 1500s many European city­ dwellers use a bowl called a chamber pot. • When the pot is full, they just toss the contents out the window, shouting "Gardy-loo!“ to warn anybody unlucky enough to be walking below.

  7. A Charmin’ Idea • In 1857 Joseph Gayettyintroduces toilet paper. • Each sheet is printed with Gayetty's signature. • Before this, people used whatever they could find.

  8. Bathroom Reading • In 1672 devoted readers can buy a fancy toilet disguised as a stack of books. • One of the most popular models of chamber pots is in France.

  9. Stop Making Scents • In 1775 Alexander Cummings patents the modern flush toilet. • The S-trap is a valve that keeps the bowl filled with water. • It allows poop to go down without letting smells come up.

  10. Sculptured Seats • In 1885 Thomas Twyfordcreates the Unitas, which is the first all-ceramic toilet • The Unitas eliminates the leaky joints that made earlier models smelly. • These ceramic toilets catch on quicklyand are covered with great decorations

  11. Minding Your Business • 1999: The Matsushita Electronic Industrial Company of Japan creates a smart toilet. • This toilet measures your weight and body-fat con­tent, and chemical sensors inside analyze your output for information about your health. • Scientists expect it to be on the market in a few years.
