Purple Flame Magic
Materials 5g of pottassium permanganate cystals, 2ml of glycerol, a porcelain tile and a dropper. Procedure Pile 5g of powdered KMnO4 crystals on a porcelain tile.Make a small depression on the centre of the pile. Using a dropper or a glass tube add carefully about 3 to 4 drops of glycerine to the depression. After a few seconds a white puff of smoke is produced followed by sparks and purple flame. Discussion This experiment demonsrtates spontaneous combustion. KMnO4 oxidizes glycerol exothermically producing heat and light.
