CrazyRussianHacker takes you through the steps of making dry ice at home with a CO2 fire extinguisher and a pillowcase. The process is simple: put the nozzle in the pillowcase and pull the trigger. The pillowcase strains the emission and you’re left with dry ice, the solid form of carbon dioxide. You’ll want a pair of gloves if you perform the experiment at home — CO2 solidifies at a temperature of 109.3-degrees Fahrenheit.
