A fairly well-known demonstration using a sparkler is the following: Bend the wire where you hold it at 90° to the active part, and insert it into the chuck of a drill. Darken the room, ignite the sparkler, and let the drill rotate slowly. A shower of sparks flies off tangent to the circular motion, much like sparks from a rotating whetstone.
