Despite its name, the Museum of Feelings, a pop-up installation devoted to sights and smells in Battery Park City in Lower Manhattan, is not a place of introspection.

On the surface, it is a place devoted to a set of positive emotions, including joy and optimism. But that is about as deep as it goes. On Tuesday, visitors spent more time looking at their own images reflected on their phone screens, because the Museum of Feelings is actually the perfect place to take a really good selfie.

The museum is not a museum at all. It is an elaborate, walk-through advertisement for Glade products, complete with some very attentive brand ambassadors dressed in costume. But the marketing aspect has not stopped visitors from standing in a line that snakes around a luxury mall.

For an installation with a three-week life span (it ends Dec. 15), the Museum of Feelings has an outsized presence on social media: The #MuseumofFeelings hashtag on Instagram is beautifully vibrant, and the attraction has a solid three-star rating on Yelp. “Make sure to take as many photos as possible and bring positive people with you,” one tipster wrote. On Saturday, 3,000 people stood in a four-hour line to attend, and the line was growing by the minute on Tuesday.
