This is one cool gadget for your holiday parties. A portable device that can create a one pound block of dry ice in around one minute. Dry ice is a superfast coolant for foods and beverages. Plus it looks really neat. It would be wonderful for Halloween festivities. The device from Hammacher Schlemm...moreer requires a connection to a cylinder of compressed liquid CO2 with a dip tube or siphon which must be purchased from local gas dealers or a welding supply shop. One 50-lb. CO2 cylinder at room temperature yields up to 11 blocks of dry ice and handling requires use of insulated gloves, also not included So it's a teensy bit complicated. Still cool though. . It sells for $499.95.
