Just grab a $20 bill (US or Canadian, it doesn't matter), make sure it's relatively dry, then use a cheap lighter (Bic comes to mind) to light it on fire. Watch it go up in flames, but make sure to drop it somewhere safe before it burns your fingers. Keep repeating this until you reach an amount you feel is appropriate.
