Novel Dry-Ice Gun Extinguishes Candle

Get a dry ice gun to extinguish a candle. Here’s how: to within 1/4″ of the edge, cut out the top of a cardboard salt box and tie a piece of rubber balloon over it. Cut a 1-1/2″ hole in the opposite end, roughening its rim with a pen knife. Load the gun with carbon dioxide gas by inserting dry ice. Aim the gun, tap the rubber, and an invisible ring of gas will smother a candle flame six to eight feet away. You can stage an amazing William Tell stunt with the gun!
