Transcript

[♪ INTRO] Look. We all poop, but pretty much nobody wants to deal with it. We don't want to touch it, smell it, look at it... And there’s a really good reason for that. While your own poop probably won't hurt you, many serious diseases, like cholera, typhoid, and polio, are all caused by microbes in human waste. Thankfully, most of us are relativel... Read More

Questions & Answers

Q: What is the purpose of the S-bend in a toilet?

The S-bend, or U-bend in modern toilets, traps water in the pipe, creating a barrier that prevents sewage gases from entering the bathroom when the toilet is flushed.

Q: How do toilet sprays work?

Toilet sprays contain essential oils, alcohol, and soap or glycerin, which create a barrier on the water's surface that traps smelly molecules, preventing them from escaping into the air.

Q: Why is it important to put the lid down before flushing the toilet?

Flushing without closing the lid can release a plume of bacteria and viruses into the air, which can settle on surfaces in the bathroom, including toothbrushes. Closing the lid helps prevent this contamination.

Q: Why do porta-potties use blue liquid?

The blue liquid in porta-potties contains biocides to kill bacteria in the waste, fragrance to mask odors, and a surfactant to mix the ingredients. The blue color helps hide the waste and indicates when the tank needs to be emptied.

Summary & Key Takeaways

• The invention of the flush toilet, specifically the S-bend, revolutionized bathroom experiences by whisking waste away and preventing sewage stink.

• Toilet sprays create a barrier on the water's surface, trapping smelly molecules and preventing bathroom odors from lingering.

• Putting the lid down before flushing the toilet helps prevent the release of bacteria and viruses into the air, reducing the risk of contamination.
