It’s 90 degrees out today. Hot enough to melt… an iceberg, perhaps?

We tried to find out at the National Building Museum’s “ICEBERGS” installation, a more than 12,000 square feet “underwater” world in the great room of the building.

The installation features soaring replica icebergs that jut in and out of a blue mesh lining meant to represent the water line. Museum-goers, who pay $16 per adult and $13 per child (or senior), can walk inside iceberg igloos or climb above the 20 foot high “water-line” to get a glimpse of the ‘bergs from above.

Everything in the museum is on theme, and the floor is covered in bean bag chairs shaped like giant shards of ice. There’s even a giant slide, which is a hit with the kids (and with us adults, too).

If you want a taste of the action, one of the icebergs is converted into a shaved ice stand — DC restaurant Daikaya is serving up Japanese kakigori shaved ice with ice cream, mochi, and made-from-scratch sauces. It’s delicious. We can vouch.

The entry costs also give you access to the entire building, too. There’s a fantastic exhibition called “Small Stories: At Home in the Dollhouse” that features miniature homes, and tons of other cool rooms to check out.

This interactive museum exhibit isn’t just for children… Every Wednesday night from 6 to 10 p.m., the National Building Museum hosts a “Late Night” at the icebergs to give adults a chance to “break the ice” between one another. Each week is different, with various musicians, restaurant vendors and activities. You’ll want to get your tickets ASAP, since they’ve already sold out for tonight’s event, which features White Ford Bronco. A schedule of the events can be found here.

The museum is open from Monday to Saturday from 10 a.m. to 5 p.m. and on Sundays from 11 a.m. to 5 p.m. “ICEBERGS” is open until September 5.
