What Is Dry Ice?
Dry ice is the solid form of carbon dioxide. Unlike the regular ice cubes chilling your lemonade, this ice has a party trick up its sleeve: sublimation. This means it doesn't melt into a puddle; instead, it transforms directly into carbon dioxide gas.
Dry Ice Temperature
Now, as much as we love its magical features, a block of dry ice boasts an extremely cold surface temperature of minus 109.3 degrees Fahrenheit (minus 78.5 degrees Celsius). That's a lot colder than your freezer's ice cream stash.
What Happens During Direct Contact?
The sensation of touching dry ice is similar to grabbing a hot pot's handle without an oven mitt. A brief touch might just leave you with some red skin, but prolonged contact? That's where the ice burn occurs.
These aren't your typical burns from heat but rather from extreme cold. The dry ice freezes your skin cells, causing an injury similar to a heat burn.

The Science Behind Ice Burns
When you touch dry ice, the freezing temperatures constrict your blood vessels, reducing blood flow to the affected area. This lack of blood can cause severe tissue damage, leading to a condition we commonly refer to as frostbite.
Symptoms of an ice burn include waxy skin, discomfort and a change in skin color.

Safety First: Handling Dry Ice
When dealing with this frosty substance, always handle dry ice with care to prevent ice burns. Wear heavy gloves and avoid direct contact with bare skin.
Remember, it's better to be safe than sorry when dancing with this chilly partner!

First Aid for Ice Burns
It's crucial to treat the burned area promptly.
Start by soaking the afflicted area in warm water for about 10 minutes. Avoid hot water, as this can cause further damage to already damaged tissues.

Apply aloe vera for some cooling relief and keep the area clean to prevent infection. If you see blisters or experience severe pain, it's time to seek medical attention.

Dry Ice FAQ
Is dry ice dangerous?
When carbon dioxide takes on a solid form, it becomes dry ice. Though dry ice has a temperature of minus 109 F, it's not inherently dangerous when stored and handled correctly.
Can dry ice catch fire?
Dry ice is not flammable and won't ignite your Halloween cauldron. However, because it turns into carbon dioxide gas, sealed containers can rupture from the pressure. So, no tight-lidded potions with this ingredient!
What happens if you touch dry ice with your bare hands?
Poking dry ice with your finger will feel extremely cold. Holding dry ice in your bare hands is not recommended and will likely result in severe frostbite.
What should you do if you burn yourself with dry ice?
You will need to treat dry ice burns like a regular burn. You should see a doctor immediately if blisters form on the skin. The burned area will need to be kept clean until it fully heals to prevent infection.
What's the risk of dry ice with younger children?
Ensure that younger children understand the risks and keep dry ice out of their playful reach. After all, no one wants an unexpected frosty surprise.

As an enthusiast with a deep understanding of the topic, I've delved into the fascinating world of dry ice and its effects on the skin. My extensive knowledge in the field allows me to provide a comprehensive overview of the concepts discussed in the article "HowStuffWorks Science Physical Science Chemistry Chemical Processes and Tests" by Marshall Brain and Austin Henderson, updated on Sep 29, 2023.
Dry Ice: The Solid Form of Carbon Dioxide Dry ice is not your typical ice found in your drink; it is the solid form of carbon dioxide. Unlike regular ice that melts into a puddle, dry ice exhibits a unique phenomenon called sublimation. This means it transforms directly from a solid to carbon dioxide gas without going through a liquid phase.
Extreme Cold: Temperature of Dry Ice The article highlights that dry ice boasts an extremely cold surface temperature of minus 109.3 degrees Fahrenheit (minus 78.5 degrees Celsius). This is significantly colder than the typical freezer, emphasizing the need for caution when handling it.
Effect of Direct Contact: Dry Ice Burns Direct contact with dry ice is likened to grabbing a hot pot handle without an oven mitt. While a brief touch may result in red skin, prolonged contact can lead to what is referred to as an "ice burn." Unlike burns from heat, ice burns occur due to extreme cold, where the freezing temperatures constrict blood vessels, reducing blood flow and causing tissue damage similar to frostbite.
Safety Measures: Handling Dry Ice The article underscores the importance of handling dry ice with care to prevent ice burns. Safety measures include wearing heavy gloves and avoiding direct contact with bare skin. The key message is to prioritize safety when dealing with this frosty substance.
First Aid for Ice Burns In case of an ice burn, the article provides essential first aid tips. This includes soaking the affected area in warm water for about 10 minutes, avoiding hot water to prevent further damage. Aloe vera is recommended for cooling relief, and maintaining cleanliness is crucial to prevent infection. Severe symptoms, such as blisters or intense pain, warrant seeking medical attention.
FAQs About Dry Ice The article anticipates common questions, addressing concerns about the safety of dry ice, its flammability (or lack thereof), and the potential consequences of touching dry ice with bare hands. It also emphasizes the importance of keeping dry ice out of reach of younger children.
In summary, the article delves into the science behind dry ice, exploring its unique properties, potential hazards, and the necessary precautions and first aid measures to ensure safe handling. The information is not only informative but also underscores the importance of understanding the characteristics of dry ice to prevent accidents and injuries.
