When you arrive at your moment of temporary insanity,please get someone to record it so we may all benefit from it, as well as pass the hat to raise funds to bail you out of jail.Kidding!------------ I'm not admitting to anything myself,but Estes model rocket dry-cell ignition systems make a great way to ignite fuzed smoke bombs that find their way into a perforated metal can which has stolen a ride on a persons rear bumper late at night on a deserted road where flash photography can capture the image of the smoke trail which a light breeze safely blows from the test track,away from any unsuspecting motorist who might happen along about then.
