Dry Ice: Uses, properties, hazards and how not to abuse it

Partying is a common trend for Nigerians.

The booming music, the dancing that continues without pause, and the whole atmosphere brightened by shimmering and vibrant outfits.

It is common practice in Nigeria to entertain either at parties, bars, clubs and discos in the most outstanding way ever.

You might even go as far as seeking out ways to provide extra fun for everyone while entertaining them. One common way of doing this is to use dry ice to create a smoky effect in your drinks.

But before you make use of dry ice in that next cocktail to create that smoky effect, take a pause and read this.

Dry ice, also known as solid carbon dioxide (CO2), is the solid form of carbon dioxide gas. Unlike regular ice, which is made of water molecules, dry ice is made by compressing and cooling carbon dioxide gas to a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). At this temperature, carbon dioxide undergoes sublimation, directly changing from a solid to a gas without going through a liquid phase.

Dry ice gets its name from the fact that it does not melt like regular ice. Instead, it sublimates, meaning it goes from a solid to a gas. This process occurs at normal atmospheric pressure, and as dry ice sublimates, it releases carbon dioxide gas.

KEY PROPERTIES AND USES OF DRY ICE

Extremely cold: Dry ice is incredibly cold, making it useful for various applications that require low temperatures. It can reach temperatures as low as -78.5 degrees Celsius (-109.3 degrees Fahrenheit).

Preservation and transportation of perishable items: Dry ice is commonly used for preserving and shipping perishable items, such as food, vaccines, and biological samples. Its extremely cold temperature helps keep the items frozen or chilled during transportation.

Special effects: Due to its ability to create a dense cloud of carbon dioxide gas when it sublimates, dry ice is used in theatrical productions, concerts, and other events to create a smoky or foggy effect.
Cleaning: Dry ice blasting is a non-abrasive method of cleaning surfaces. It involves using dry ice pellets propelled at high speeds to remove dirt, contaminants, and unwanted substances from various materials and surfaces.

Carbonation: Dry ice can be used to carbonate beverages or create carbonated desserts. When added to liquids, it sublimates, releasing carbon dioxide bubbles and creating a fizzy effect.

DRY ICE IN DRINKS

Dry ice can be used to create a visually stunning and unique presentation for drinks. When added to beverages, dry ice releases a dense, white fog-like vapor, creating a captivating and dramatic effect.

However, if you must use dry ice in your drinks, it’s important to use it safely and responsibly. Below are some guidelines to follow.

Purchase and handle dry ice with care: Dry ice is extremely cold and can cause frostbite if it comes into direct contact with the skin. Always use insulated gloves or tongs when handling dry ice. Purchase it from a reputable supplier and transport it in a well-insulated container.

Never ingest or touch dry ice directly: Dry ice should never be consumed. It is not meant for ingestion and can cause harm if ingested. Additionally, avoid touching dry ice directly to prevent frostbite.

Use food-grade containers and ingredients: When incorporating dry ice into drinks, ensure that all containers, utensils, and ingredients used are food-grade and safe for consumption.

Allow the dry ice to sublimate completely before drinking: Before serving the drink, make sure the dry ice has fully sublimated and turned into gas. Do not ingest the drink while dry ice is still present in solid form.

Add dry ice safely: Place a small piece of dry ice (about the size of a thumbnail) into the drink just before serving. It’s important not to add large pieces or excessive amounts of dry ice, as this can cause rapid sublimation and may lead to pressure buildup or splashing.

Provide proper warning and instructions: If you serve drinks with dry ice, make sure to inform your guests about the presence of dry ice and provide clear instructions on how to handle the drink safely. Warn them not to touch or ingest the dry ice and advise them to wait for it to fully sublimate before drinking.

The primary purpose of using dry ice in drinks is for visual effect rather than consumption. It’s crucial to prioritize safety and ensure that your guests are informed about its presence and the proper handling procedures.

USING DRY ICE FOR SPECIAL EFFECTS

Dry ice is commonly used for special effects due to its ability to create a dense fog or smoke effect. Here are some popular ways dry ice is used for special effects:

Fog and smoke effects: Dry ice is widely used to create atmospheric fog or smoke effects in weddings, theatrical productions, concerts, haunted houses, and other events. By placing dry ice in hot water or using special fog machines designed for dry ice, the sublimation of the dry ice creates a thick, low-lying fog that can add an eerie or dramatic ambiance to a performance or event.

Visual effects in film and photography: Dry ice is employed in the film and photography industry to create various visual effects. It can be used to simulate steam or smoke in a controlled manner, adding depth and realism to scenes. Dry ice is often used in combination with lighting techniques to enhance the effect and create a captivating atmosphere.

When using dry ice for special effects, it’s essential to follow proper safety guidelines. Ensure proper ventilation to prevent the buildup of carbon dioxide gas, use insulated gloves or tongs when handling dry ice, and inform participants about the potential hazards and safety precautions to ensure a safe and enjoyable experience.

HEALTH HAZARDS OF INGESTING DRY ICE

Dry ice should never be ingested, as it can be harmful to health. Here are some health hazards associated with ingesting dry ice.

Frostbite or burns: Dry ice is extremely cold. If ingested, it can cause severe frostbite or burns to the mouth, throat, and digestive system, leading to tissue damage.

Internal injuries: Ingesting dry ice can result in internal injuries, especially if swallowed in large pieces. The extreme cold temperatures can cause damage to the esophagus, stomach, and other organs.

Rapid release of carbon dioxide gas: Dry ice sublimates and releases carbon dioxide gas as it warms up. Ingesting dry ice can lead to the rapid release of carbon dioxide gas inside the body, causing bloating, discomfort, and potentially dangerous levels of gas buildup.

Asphyxiation: Ingesting dry ice can cause a significant buildup of carbon dioxide gas in the body. In high concentrations, carbon dioxide can displace oxygen, leading to asphyxiation or oxygen deprivation. This can be life-threatening.

If someone accidentally ingests dry ice, it is crucial to seek immediate medical attention. Contact a poison control center or emergency medical services for appropriate guidance. Do not induce vomiting unless instructed by a medical professional.

So, the next time you’re served that Cocktail with white fog-like vapor and you’re about to take it in that smokey form, reflect on the health dangers attached to it and ask yourself if it is really worth it.
