Answer:
Hey!
Here's your answer:-
Homemade Dry Ice Materials
CO2 fire extinguisher or carbon dioxide tank.
Cloth bag
Heavy-duty gloves.
Duct tape (optional)
Carbon dioxide fire extinguishers are labeled as such. If a fire extinguisher doesn't specify "carbon dioxide" assume it contains something else and won't work for this project.
Make Dry Ice
All you have to do is release the pressure on the gas and collect the dry ice. The reason you use a cloth bag is that it will allow carbon dioxide gas to escape, leaving just the dry ice.
Put on the heavy-duty gloves. You don't want to get frostbite from the dry ice!
Place the nozzle for the fire extinguisher or the CO2 tank inside the cloth bag.
Either clamp your gloved hand around the mouth of the bag or else tape the bag onto the nozzle. Keep your gloved hand clear of the nozzle.
Discharge the fire extinguisher or, if you are using a CO2 canister, partially open the valve. Dry ice will immediately begin forming in the bag.
Turn off the fire extinguisher or close the valve.
Gently shake the bag to dislodge dry ice from the nozzle. You can remove the bag and use your dry ice.
Dry ice sublimates quickly, but you can extend how long it lasts by storing the bag in the freezer.
