And Finally …
On Saturday, a swimming pool full of rainbow sprinkles will open in Los Angeles — at last.
After a popular run in New York last summer, the pop-up Museum of Ice Cream has moved into an arts district warehouse, where it will celebrate all things milk, cream and sugar for the next five weeks.
The museum created 10 “reimagined” installations, including a melted Popsicle jungle, a walk of fame — featuring “Vanilla Ice” of course — and a live mint “grow house.”
The project is the brainchild of Maryellis Bunn, a design strategist, and her boyfriend, Manish Vora, a former investment banker.
Asked why they chose Los Angeles, Mr. Vora said it was a natural choice.
The museum is arguably as much a celebration of Instagram culture as ice cream. The Willy Wonka-like backdrops at the New York installation became a major selfie attraction. (Mr. Vora said visitors comprised a “heavy millennial set.”)
A flavor of commercialism is also hard to ignore. American Express and Dove Chocolate are among the sponsors. A gift shop sells mini cone earrings ($8), sprinkle socks ($14) and a pink Ping-Pong table ($10,500).
Thankfully, real ice cream is included in the ticket price ($29 for adults and $18 for children and seniors). California creameries will be on hand with a rotating “scoop of the week.”
The museum runs from April 22 to May 29.
