What is the lifespan of dry ice? Read on to find out. Bringing dry ice on a camping trip or to a barbeque will ensure your ice cream, popsicles, or frozen veggies stay frozen for a long time. But, just how long will your dry ice last? Depending on how you’re storing your dry ice will determine just how long it’ll last. By using the correct method, you can prolong the lifespan of your dry ice and all of your favorite frozen treats you brought along for the ride. How Long Is the Lifespan of Dry Ice?This will vary due to how you’re storing it and the size of the brick you have. Based on a whole, five-pound block (that is intact, not broken up), the lifespan of dry ice is 18-24 hours in a cooler. Outdoors, dry ice should last about 3-5 hours and in liquid for up to 45 minutes. Since dry ice sublimates and turns to gas as it evaporates, you should plan for how much it may sublimate before you need to use it. If you buy 20-25 pounds, you can expect to have about 15 pounds of dry ice the next day if appropriately stored in a cooler. We recommend purchasing as close as possible to the event you need it for, so you can make the most out of the lifespan of dry ice. How Do I Make My Dry Ice Last Longer?To prolong the lifespan of dry ice, here are a few tips we can recommend:

FOLLOW ALL SAFETY INSTRUCTIONS WHEN TRANSPORTING, USING OR STORING DRY ICE! DRY ICE IS HARMFUL IF EATEN OR SWALLOWED! IF INGESTED, SEEK MEDICAL HELP IMMEDIATELY! NEVER PUT DRY ICE INTO ANY FOOD, DRINKS OR LIQUIDS THAT MIGHT BE INGESTED BY HUMANS OR ANIMALS! How long does dry ice last? The answer depends on how you store it. Five pounds of dry ice in a cooler will last about 18-24 hours. Without any protection, it will last for about 3-5 hours. When stored in liquid, it lasts for only 15-45 minutes. Dry ice is mainly used to keep food and drinks fresh. It’s a great alternative to regular ice, especially while camping. Unlike regular ice, dry ice is frozen carbon dioxide. It forms at -109.3°F (-78.5°C) — that’s cold enough to cause frostbite! Carbon dioxide is the gas that we exhale when breathing. It’s also what plants use in photosynthesis. It’s impossible for dry ice to be in liquid form. So how does it “melt” and how long does dry ice last? When stored in a good cooler, dry ice lasts about 18-24 hours. The time it lasts varies depending on how you store it, how much ice you have, and how good your cooler is. Dry ice is likely to last longer than regular ice, but it still has a relatively short shelf life. If you plan to use it, you should buy it right before you actually intend to use it. Of course, if you don’t protect your dry ice, it will go bad faster. The act of solid dry ice turning to gas form is “sublimation”. Dry ice stored in a cooler will sublimate at the slowest rate. In LiquidDry ice doesn’t last very long when stored in a liquid. The liquid causes the dry ice to warm up and vaporize, turning back into gas. When stored properly, a 5lbs (2.26kg) solid block of dry ice will last for only 15-45 minutes. Dry ice is a very popular product for parties, especially during Halloween. People will place dry ice in a bowl of liquid to create a foggy effect. This is popularly used in drinks like punches and cocktails. Out In The OpenIf you leave a 5lbs (2.26kg) block of dry ice outside without a way to protect it, it will last for about 3-5 hours. In A CoolerA 5lbs (2.26 kg) block of dry ice in a cooler will generally last anywhere from 18-24 hours. Eight to twelve pounds (3.62-5.44kg) will last for 24-40 hours, and 13-20lbs (5.9-9.07kg) will last for 40-60 hours. So far, storing dry ice in a cooler is the most efficient method. Keep in mind that the type of cooler matters. High-quality coolers will keep dry ice longer than standard coolers. But standard coolers are definitely better than cheap styrofoam containers. High-Quality CoolersYou can use dry ice with most coolers, but high-quality coolers are better suited for the task. High-quality coolers tend to have ventilation systems built into them. That means you don’t have to worry about venting the lid. The best coolers for dry ice are usually roto-molded or plastic. Standard CoolersStandard coolers work well for dry ice, but they might not have enough insulation. Without built-in ventilation, you’ll need to rig the lid to stay slightly open. Styrofoam CoolersStyrofoam coolers are best if you plan to use dry ice in a single day. They have a straightforward design but don’t handle insulation all that well. How To Check If Your Cooler Is Compatible With Storing Dry IceAny cooler is compatible with dry ice. You just need to know how to store it. As I mentioned above, a high-quality cooler will be better, but it’s not necessary. VentilationIt’s good to have a cooler with a ventilation system or drainage spout. It allows for carbon dioxide to escape as it sublimates. Doing this means you can keep the cooler’s lid closed without much fuss. InsulationThicker coolers work better to keep the cold in. When possible, choose a cooler that’s about 3in (7.62cm) thick. It’s also recommended to get a cooler with some padding inside. This offers your cooler protection because dry ice can damage the plastic. What If You Don’t Have These Features?If you don’t have these extra things in your cooler, that’s okay. You can line your cooler with a styrofoam cooler or cardboard to protect the plastic. You should also wrap the dry ice in some newspaper. The newspaper will protect your cooler and food from the dry ice. If your cooler doesn’t have ventilation or a spout, you’ll need to vent the lid. How To Make Dry Ice Last LongerThis is pretty simple — store it in a cooler. Use a high-quality cooler if possible. Your cooler should have insulation, and the lid should be loosely closed. You DO NOT want to use an airtight cooler. The gas needs a way to escape as it sublimates. If it has nowhere to go, you will have a build-up of carbon dioxide gas inside your cooler. If enough dry ice sublimates, there will be too much pressure inside your cooler. Eventually, it could cause the cooler to burst. You should also keep your cooler located in the coolest spot possible. This will keep your cooler from warming up too quickly, which lets your dry ice last longer. Be sure to place the cooler somewhere well-ventilated for the dry ice to safely dissipate. For your safety, you won’t want to breathe in too much of the gas. Another way to keep your dry ice lasting longer is by wrapping it in several layers of newspaper. Newspaper is an excellent insulator and can extend the life of your dry ice for a few hours.

Shipping companies frequently use dry ice to keep their products cold. It’s more effective than regular ice during the warmer months because it doesn’t melt. Some popular uses of dry ice include:
Since dry ice is great at preserving food and beverages, it’s the perfect product for camping! It’s a given to have food while camping. Unless you want to live on dehydrated food and granola bars for the whole trip, you’ll need a way to keep your food cold. Using regular ice when camping is a problem. It’s heavy to lug around and doesn’t last very long, even in a cooler. More often than not, it leaves you with a cooler full of water and warm food. This is where dry ice comes in. Dry Ice Lasts LongerDry ice is much better than regular ice because it lasts longer. When stored in a cooler, 5lbs (2.26kg) of dry ice can last up to 24 hours. Regular ice will melt hours before that. Also, because dry ice sublimates rather than melts, you won’t have a mess after the dry ice has gone. Dry Ice Is LighterDry ice is much lighter than regular ice. Five pounds (2.26kg) of dry ice fills more space than five pounds of regular ice. Which means you’ll need less dry ice to cool your food. No one likes to lug around a lot of weight while camping, so lightweight dry ice is ideal. It’s especially handy for backpackers. Here are some clever ways you can use dry ice while camping:
What To Consider When Using Dry IceHow much dry ice you need depends on the size of your cooler and how long you’ll be camping. It also depends on your cooler’s insulation and what kind of food you’ll bring. The size of your cooler is less important than the time you need your food to stay cool. For example, 5lbs (2.26kg) of ice will be enough for both 20 quarts and 100 quarts for 12 hours. But you’ll need even more ice to keep food cool overnight. You’d need about 50-100lbs (22.68-45.36kg) of dry ice to keep your food cool for 96 hours in a 100-quart cooler. But a 20-quart cooler can’t handle keeping food cool for 96 hours, regardless of how much ice you have. Smaller coolers usually need a bit more ice to stay cooler since they don’t hold the cold very well. One to five pounds (0.45-2.26kg) of dry ice is suitable for 12 hours for coolers under 20 quarts. You should bring 5-10lbs (2.26-4.54kg) of dry ice if you want to store food for 24 hours. Ten to twenty pounds (4.54-9.07kg) can keep food cool for 72 hours.

You can even pack frozen food like ice cream or popsicles in your cooler. You just need to know how to correctly pack your food items. You should wrap the dry ice in newspaper to prevent damaging your cooler or food. If you just need to keep your food cool, you can pack the dry ice at the bottom of the cooler. You can put a layer of cardboard on top of the ice to separate the food. If you want to keep your food extra cold or frozen, you should wrap the ice around the food. Distribute the ice throughout the cooler so that it surrounds your food. Fill in any empty spots with newspaper for extra insulation. Or, if your dry ice is in large blocks, pack your food at the bottom of the cooler first. Then, pack the dry ice on top. How To Handle Dry IceDry ice is a handy product that can keep your food fresh for longer than regular ice. But remember that it’s frozen carbon dioxide. You need to consider some safety precautions when handling and storing it. Here is a list of dos and don’ts when it comes to handling dry ice: Do:
Don’t:
Dry ice is toxic when inhaled. If a person inhales too much carbon dioxide, they will fall unconscious and may even die. Because dry ice is so cold, it can harm your skin if you touch it. If you accidentally touch it for a moment, your skin will turn red. But if you hold it for any longer, you can develop frostbite. Where Can You Find Dry Ice?Dry ice is surprisingly easy to find. Most grocery stores have it. If you can’t find it at your local grocery store, you can find it at some of the larger chain stores. The average cost of dry ice is $1-3 per pound. Generally, the less you get, the more it will cost. It’s cheaper to go through a dry ice manufacturer than a retailer. For example, Walmart usually sells its dry ice for $1.30-1.50 a pound. But, larger suppliers may sell 50lbs (22.7kg) for about $35.00. Here is a list of stores that sell dry ice:
If you can’t find it at your grocery store, try purchasing dry ice from the suppliers:
If all else fails, you can try to buy some dry ice from your local ice cream parlor. They don’t usually sell it, but if you’re out of time and in a bind, they might be willing to give you some. You might be able to find dry ice at your local gas station as well, although this isn’t very common. You May Also Like: How Hot Is A Campfire? Wood Tips, Temperature, Color Facts FAQCan a Standard Freezer Store Dry Ice?You should never store your dry ice in a freezer. Carbon dioxide becomes dry ice at very cold temperatures of -109.3°F (-78.5°C). But, standard freezers stay at about 0°F (-18°C). Freezers are not made to withstand temperatures as cold as dry ice. The dry ice will mess up the thermostat, which will cause your freezer to shut down. Can Dry Ice Melt?Dry ice is frozen carbon dioxide. Carbon dioxide can never become a liquid, so dry ice cannot melt. Dry ice becomes solid at temperatures of -109.3°F (-78.5°C). As it warms up, it sublimates, skipping the liquid stage and becoming a gas. Can Dry Ice Ruin a Cooler?When storing dry ice in a cooler, you need to keep the lid loosely open. If you use an airtight cooler, the gas can’t escape when it sublimates. The build-up of gas can cause your cooler to explode. These extreme temperatures can cause damage to the bottom of your cooler. To prevent this, place a layer of styrofoam or cardboard at the bottom of your cooler before adding the dry ice. Can You Make Your Own Dry Ice?You can make your own dry ice, but it’s usually cheaper to buy it. To make it yourself, you’d need a CO2 fire extinguisher or pressurized tank of carbon dioxide. You can purchase carbon dioxide online or from sporting goods or cooking stores. Basically, you would place the nozzle of the CO2 container inside a cloth bag. Clamp your hand around the opening of the cloth bag, and discharge the bottle of CO2. The bag allows the gas to escape, leaving behind dry ice. Can You Place Dry Ice And Regular Ice In The Same Cooler?Yes, you can place dry ice and regular ice in the same cooler. Dry ice is great at keeping regular ice cool. Rather than melting in a few hours, dry ice can keep regular ice solid for a couple of days. This is handy if you want regular ice for your drinks but need it to last longer. How long does it take 5 lb of dry ice to melt?It takes about 24 hours for five pounds of dry ice to turn from solid to gas — even when stored in a cooler. So if you buy it a few days in advance of your Halloween party, it won't last. Follow this tip: Plan for a dry ice run right before you need it.
How long will 10 lbs of dry ice last?Generally speaking, 10 pounds of dry ice will last up to 24 hours in a standard 25-quart cooler—but there are a lot of factors at play. You'll also want to consider the types of food you're storing (frozen or refrigerated), the size of your cooler, any ambient conditions and the duration of storage.
How much dry ice will last 2 days?For dry ice, plan on using 5 to 10 lbs. for each 24-hour period, depending upon the quality of the insulated shipping container. This will keep everything frozen in a container up to 15 quarts in size.
How much dry ice do you need for 5 days?How much dry ice will you need? According to our experienced branch manager at our Decatur, Illinois location, a good rule of thumb to go by is “10 lbs. of dry ice per cooler per day.”
