How to Pack Dry Ice in a Coolerに挑戦したい方へ、役立つ ヒントをご紹介します。

Do not use a cheap styrofoam cooler from a gas station. That’s like using a paper hat to bail out a sinking boat. You need a heavy-duty, rotomolded cooler—the kind that costs as much as a used sedan. Brands like Yeti, Pelican, or even a cheap knockoff with a thick wall will do. The walls must be thick, because dry ice laughs at puny insulation.

Also, check for a pressure-relief valve. Most quality coolers have a little plug or vent built into the lid or side. If yours doesn’t, you’re building a carbon dioxide bomb. Dry ice sublimates and builds up pressure. A sealed cooler with no vent will eventually pop open like a champagne cork—except the “champagne” is frozen gas that can suffocate you. Fun fact: in 2018, a guy in Michigan blew his cooler lid through his garage ceiling. His burger meat survived, but his pride did not.
