The Portable Dry Ice Maker allows you to make your own 1 pound blocks of dry ice anytime you want. You simply need to aquire a cylinder of compressed liquid CO2, connect it to this device, open the valve and watch as the CO2 fills the device's chamber, vaporizes, expands, freezes and becomes a block of -109.3° F dry ice in around 60 seconds. You can use dry ice for a number of things, including keeping food and beverages cold at parties (it doesn't melt like regular ice!), amazing people with cool science tricks, creating a smoking swimming pool or using it in other nefarious things we won't mention (er, ok see the dry ice bomb video below to see how not to use it).
