Tucked into a Park Slope storefront at 372 Fifth Avenue sits one of New York's most delightfully absurd retail experiences: the Brooklyn Superhero Supply Co. This isn't some pop-up capitalizing on Marvel fever. It's a fully committed superhero outfitter that's been serving the cape-wearing community since 2004, complete with professional-grade equipment testing facilities.

Walk in and you'll find shelves stocked with bottled chaos, oxygen gum for underwater missions, cans of courage, and jars of antimatter. But the real attraction sits in the back: a cape fitting room with a three-fan wind tunnel mounted on a pedestal. Climb the steel steps, don your cape of choice, and feel the full force of industrial fans simulating high-altitude flight conditions.

Testing Your Invisibility Status

The store also operates an invisibility testing center—because apparently there's a significant problem with people not knowing whether they're visible or not. You can purchase invisibility itself (their most popular product), invisibility paint, or various sprays depending on your concealment needs. The testing center ensures your purchase actually works before you attempt any covert operations.

For villains looking to reform, there's even a devillainizing chamber that asks diagnostic questions, determines what type of villain you are, and "takes care of the problem."

The Secret Behind the Store

Here's where it gets wholesome: the entire operation is a front. Behind a sliding bookcase lies the real mission—826NYC, a nonprofit writing center providing free tutoring to underprivileged students ages 6-18.

Founded by novelist Dave Eggers and educator Ninive Calegari, 826NYC needed to operate in retail-zoned space. Rather than fight zoning regulations, they leaned in hard. Every superhero product sold funds the tutoring programs. Students help staff the store. The entire absurdist setup creates a world where imagination and literacy work hand-in-hand.

The concept proved so successful that it spawned locations across the country, each with themed storefronts: a pirate supply store in San Francisco, a spy shop in Chicago, a time travel mart in Los Angeles.

What's Actually for Sale

The inventory reads like a hero's shopping list:

Utility belts (new and vintage models)
Grappling hooks for urban scaling
Deflector bracelets (Wonder Woman style)
Secret identity kits
Tights and masks in various sizes
Wall-scaling suction cups
Various bottled concepts (antigravity, chaos, gumption)

Every item comes with deadpan product descriptions and often hilariously specific use cases. A can of "courage" might note it's "especially effective before job interviews or confronting your landlord."

The store operates as a real business—you can actually purchase these items, either in person or through their online shop. Proceeds support writing workshops that serve over 3,000 students annually.

So yes, there really is a place in Brooklyn where you can test-drive capes in a wind tunnel, verify your invisibility, and stock up on bottled chaos. And somehow, that's the cover story for the even better truth underneath.
