Hydrogen Peroxide is a powerful oxidizer. Just drop some of a 20% solution on your skin and see what happens.
Which makes it an ideal fuel for jet packs.
Ha! I've used 40%. As a kid, an older cousin was staying with us one Summer, and I got a cut, and grabbed the, well, "a" peroxide bottle. Little did I know, it was for her hair.
Certainly killed any germs, not to mention bleaching skin edges of the cut.
