Please be aware that potassium permanganate is a powerful oxidizer. The
crystals can cause spontaneous combustion under the right conditons. You may
have seen a demonstration in high school chemistry where-in glycerin was
poured over the crystals with spectacular effect. Instant fireworks, no
matches required.
