Just in time for that Halloween fog machine, this strange looking contraption will let you make as much dry ice as you want. Just add a canister of compressed liquid CO2, and it’ll do the rest.
The Portable Dry Ice Maker can crank out a one-pound block of dry ice in less than a minute. For those of you who don’t know about dry ice, it’s a super-cold ice that chills out at a teeth-chattering negative 109.3° F (-78.5° C). Although its practical use is to keep food and drinks cool for long journeys, it’s best known among the geek set for the awesome low-hanging fog that it produces when immersed in warm water.
So if you need to freeze a lot of stuff, or are just looking for that cool fog effect, you can pick one up form Hammacher Schlemmer for $499.95.
