In brief

You’ll create dry ice at home using a CO₂ fire extinguisher and a pillowcase—great for experiments or special effects. This method leverages adiabatic cooling from depressurized CO₂, producing clean, residue-free dry ice. Best for those with access to a CO₂ extinguisher and adult supervision.

Questions & answers

What type of fire extinguisher is needed?

A CO₂ fire extinguisher, typically found in kitchens or equipment rooms, marked with servicing labels or holes.

How much dry ice can be made from one extinguisher?

The creator used a 5lb CO₂ extinguisher to produce about 2 lbs of dry ice.

Description from the creator

Here's how to make dry-ice at home, or wherever you feel like it! All you need is a pillow case, and a CO2 fire extinguisher.

WARNING:

Dry Ice is extremely cold! (-78C/-109F) and can cause instant frost-bite to exposed skin. This project should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in serious injury. Use of this video content is at your own risk.

Project History & More Info:

It cost just under $30 to refill the tank to get about 2 lbs of dry-ice. Contrasting that with the cost of dry-ice at the local grocery store ($1.00/lb) doesn't make financial sense, but this method is much more fun!

If pressurized liquid CO2 is quickly depressurized, the CO2 expands to a gas, and cools its surroundings. This is called adiabatic cooling. Because the CO2 sublimates directly into a gas, it's very clean and doesn't leave behind any residue.

Some fire extinguishers utilize CO2 as the medium for suppressing fires. These types are mainly found in restaurant kitchens, mechanical rooms, and in areas that hold sensitive equipment like computers.

CO2 fire extinguishers are usually charged with food grade CO2 and are referred to in terms of pounds. For example, a 5lb CO2 extinguisher is charged with a 5 lb weight of liquid CO2.

CO2 fire extinguishers are marked with stickers, or holes punched in the servicing labels. They also have unusually large discharge horns, and no pressure gauges.
