Bill Gates doesn't want your toilet to stink and he's partnering with firmenich, (The company behind some high end cologne) to create a 'Scent-Swapper'' to stop bad scents once and for all. The team collected stool in India, Africa, the U.S and Switzerland and tested it in heat, humidity, and ventilation to see what molecular compound creates the bad smell.
Scent-Swappers' were created to block receptors from that compound. Similar to technology used in noise cancelling headphones. So even though the smell still exists, 'Scent-Swappers' tricks your brain into ignoring it. You might never have to smell a stinky toilet ever again.
