Make your own Dry Ice

I absolutely must have this … I will disco all day long 24/7!

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).

Upon opening the cylinders valve, CO2 is forced into the devices chamber, where it vaporizes, expands, and becomes extremely cold; excess vapor is vented through its vertical filter slots, and the remaining vapor accumulates in the chamber and is compressed into a 7" L x 3" W x 2" D block of dry ice.
