Warning: This reaction makes small amounts of chlorine gas and should be performed outside or in a fumehood.

Simple get some potassium or sodium iodide and dissolve in a minimal amount of water. Then add an equal amount of concentrated hydrochloric acid. Check this new volume and measure out five times more 3%hydrogen peroxide. Mix together the two solutions and let stand for ten minutes. Filter the iodine.
