5 Things to Know About Using Dry Ice in a Cooler

Dry ice is far colder than regular ice It sits at around -109°F, while water ice maxes out at 32°F. Regular ice packs or chilled water warm up fast and leave a soggy mess.

It sublimates into gas, not liquid Dry ice turns directly from solid to carbon dioxide gas, so there is no water buildup inside your cooler. No soggy food or wet gear.

A few pounds can keep things frozen for days In a well-insulated cooler that is pre-chilled, dry ice can keep contents frozen or near-frozen for two to three days, sometimes longer.

Do not seal the cooler airtight Dry ice expands as it turns to gas. Sealing it tight can cause pressure to build up, popping the lid or even damaging the cooler.

Handle it with care Dry ice can cause frostbite on skin. Use gloves or tongs, and store it in a ventilated area to avoid carbon dioxide buildup in enclosed spaces.
