Portable Dry Ice Maker. Perfect for those times when ice won’t cut the mustard [eh? – Ed], this machine promises to deliver more coolness per square inch than a 50 foot iceberg in your back garden. Hook up a liquid CO2 cylinder, pump the gas and a minute later extract your 7 inch cube of dry ice. One small tip – wear gloves, OK? $499.95.
This is the portable device that is capable of producing a 1 lb. block of dry ice in as little as 60 seconds for keeping foods and beverages cold at picnics and parties. At -109.3 F, dry ice is a more effective coolant than regular ice, and it wont melt, but instead sublimates to odorless CO2 gas. The device requires connection to a cylinder of compressed liquid CO2 with a dip tube or siphon (not included, cylinder with dip tube/siphon must be purchased from local gas dealers or welding supply shops).
