Dry ice is not a toy. It can freeze your tongue if you lick it (please don’t, I know it looks like a giant mint). It can also cause cold burns on your skin. And if you put it in a sealed container of water, it will explode. That’s how kids make “dry ice bombs” in bad YouTube videos. Do not be that kid. Be the adult who packs a cooler like a pro, impresses everyone at the tailgate, and keeps the beer cold through Armageddon.
Remember: vent it, wrap it, respect it. Now go forth and chill with confidence. And if you hear a faint hissing from your cooler, that’s just science reminding you who’s boss.
