Watch Iodine Take Down Germs Under the Microscope

March 19, 2026

Hey everyone! I stumbled across this video and just had to share it. You know how we use iodine for cuts and all that, but have you ever actually seen it in action against those tiny little germies?

This video shows exactly that, and it's pretty wild to watch. They put 2% iodine on a slide with some bacteria, and you can literally see the iodine just… doing its thing. It's like a tiny, microscopic battle happening right before your eyes. Pretty cool to see science in real-time like that!

It definitely makes you appreciate how effective those common household remedies can be. Give it a watch!
