6 Toilets From History, and What They Taught Us

3 min read

This episode of SciShow is brought to you in partnership with Gates Notes. You can go to https://www.gatesnotes.com/Development/10-years-of-reinventing-the-toilet to read about the latest innovations in toilets and sanitation, and to learn more about the “Reinvent the Toilet Challenge,” which is celebrating its 10th anniversary this year.

Across the world, and throughout history, different peoples have developed different ways to deal with their own waste. And while they didn’t always nail the design, their efforts to keep themselves safe have led to the thrones and sanitation systems we know and love today.
