Details

Everyone enjoys a good explosion or long distance launch.  Learn to build your own canon project uses a simple ingredient – dry ice (frozen carbon dioxide) which goes directly from solid to gas. The process called sublimation releases a lot of the built up pressure.  Consider this…1 pound of dry ice turns to gas and gives you 250 liters of gas! That’s a lot of gas and a lot of latent propellant. The water fast tracks the form change of the dry ice creating an explosive propellant.
