"Toilet plumes" are a thing

Ok time for a gross one! When you flush the toilet with the lid up a plume of bacteria and water gets fired up into the air in a microscopic cloud. This includes droplets of bog water that land on surfaces nearby, but also tiny aerosol particles of... whatever was in the toilet. This can contain quite dangerous germs. Normally this isn't anything to worry about, but has been investigated as a way that tummy bugs get spread around on enclosed places like planes and cruise ships.
