This July, Sub Zero Nitrogen Ice Cream is throwing a birthday party—and you’re invited, especially if you’re the kind of person who thinks science is best served at -321°F with a side of marshmallows and Pop Rocks.
On Saturday, July 19, from 2 to 4 p.m., participating Sub Zero locations across the country (yes, including Simi Valley) will be scooping up free servings of their new Big Blast Sensation flavor in honor of National Ice Cream Day and their 20th anniversary. That’s right: free ice cream, no strings attached—unless you count sticky fingers.
If you’ve never been to Sub Zero, here’s the gist: they don’t scoop from a freezer. They flash-freeze your custom creation with liquid nitrogen right in front of you, complete with dramatic fog clouds that make your kids ooh and your teens maybe raise an eyebrow. It’s part edible chemistry experiment, part frozen dessert, and entirely theatrical.
This year’s celebratory flavor, The Big Blast, is a time-traveling sugar bomb: cotton candy ice cream studded with marshmallows and Pop Rocks. Yes, Pop Rocks—the fizzy candy that makes your mouth feel like a Fourth of July sparkler. It’s exactly the kind of treat that delights five-year-olds and unlocks some core memories for the grown-ups.
Sub Zero has built its brand on being all about options: dairy-free, keto, soy-based, or just plain picky? No problem. The make-your-own format means everyone can get in on the fun, whether you’re avoiding allergens or just have a deeply held belief that gummy bears and cheesecake bites belong together.
Founded in Utah in 2005 and now a coast-to-coast franchise, Sub Zero’s story includes a memorable appearance on Shark Tank and a strong STEM-infusion to their branding. Many franchisees were once customers themselves—some even first met Sub Zero at their own weddings (imagine telling your future spouse you want liquid nitrogen at the reception).
So mark your calendar, grab the kids, and prepare for some frosty fun. Even if you’re not usually one to brave mid-July lines for a free scoop, this one comes with a puff of science and a pop of nostalgia. Just maybe wear shoes you don’t mind getting sticky.
