what is dry ice -
Dry Ice is the common name for solid carbon dioxide (CO2). It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas (This process is known as sublimation).

how to make dry ice -

It is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2.
The liquid is then allowed to expand under a reduced pressure to produce CO2 snow, and finally, this snow is compressed by a hydraulic press into convenient Dry Ice blocks, slices or pellets.
The density of the compressed CO2 snow depends on the applied pressure and the pressure time. The density of the Dry Ice block can reach maximum at a temperature of -78.64°C.
