Make Dry Ice at Home With Fire Extinguisher – Dry ice or frozen CO2 is extremely cold: -109.3 oF (-78.5 oC). It’s so cool. And it is usually uses for keeping things frozen, particularly as a refrigerating system in the shipping and cooling industry. Sometimes we use the dry ice for doing experiments at home and school.
We can make dry ice at our home by using a soda maker or by using a fire extinguisher. They serve as a ready source of compressed liquid CO2. We already discussed the production of dry ice at home with the soda maker. Now let’s read how it become possible through a fire extinguisher.
You better handle dry ice with heavy duty gloves to avoid frostbite.
Try it yourself
- A pillow cover / A cloth bag
- Fire extinguisher (Look for stickers or markings on the side of the tank that indicate “Carbon Dioxide” or “CO2”.)
The Fire extinguisher is a device to suppress fires. It uses compressed liquid CO2 as a medium to cool the surroundings. When the pressurized CO2 releases quickly to the atmosphere it depressurized. While the process, CO2 expands to a gas, it cools the atmosphere through adiabatic cooling.
Step 1: Wear gloves.
Step 2: Place the nozzle of fire extinguisher in the cover and clamp the mouth of the bag with hand.
Step 3: Discharge the fire extinguisher, immediately dry ice started to form in the bag.
Step 4: Turn off the fire extinguisher. After shaking the bag seperate it from the nozzle.
Step 5: Dry ice is ready. Use it for your experiments and make fun.
