Beakman's World: Why do Feet Smell?
  • Science → Microbiology → Bacteria
  • Science → Human Anatomy → Feet
Beakman explains that shoes stink because of the bacteria on your feet. He uses a microscope to quickly show that there are bacteria everywhere and then a short animated clip to show how your feet produce oil and sweat that the bacteria eat. This creates smelly biproducts to make your feet stink. He then does a DIY bacteria growth experiment where he grows bacteria from his sweaty feet in a jar of gelatin.
