Kickstart: Lizzo brings out the fabulous with a plexiglass flute

Musician Lizzo made some news when she played a 200-year-old crystal flute once owned by President James Madison — and now part of the Library of Congress' flute collection — at a concert.

But that wasn't the only flute she played during a visit to the library. She also picked up a plexiglass flute (with permission from library archivists) and performed in the library's main reading room, a moment captured in a brief video posted on the Library of Congress' Twitter account.

"It is also very rare and was manufactured when the material was first invented," the Library of Congress noted.

The 1937 flute is one of nearly 1,700 owned by the library, making up the largest collection in the world.

Although not as exciting as Lizzo, pipe maker Uponor Corp. also has a reason to celebrate as it marks the 50th anniversary for cross-linked polyethylene pipe, or PEX.

The Finnish company first began making PEX in 1972 and it was initially used for underfloor heating. But the product's "thermal memory" quickly made it popular for a range of easy-to-install plumbing jobs.

"What started in Wirsbo, Sweden, in 1972 not only changed the industry of underfloor heating, drinking water and radiant cooling applications but the lives of many people," Uponor President and CEO Michael Rauterkus said in a news release.

For its 50th year in production, Uponor has launched PEX Pipes Blue, what it says is the first bio-based PEX pipe, made using material created through a mass balance approach.

The blue PEX has a carbon footprint that is 90 percent smaller than traditional PEX, the company said, and allows an entire construction project to be more sustainable.

Two staples of American childhood — Lego and Capri Sun — are appealing to adults with new marketing projects.

Toymaker Lego is hosting a series of events for adults only to unwind and play with plastic bricks. Termed "Lego Lates," they're intended to "be the solution for stressed-out grownups seeking a creative outlet," our sister paper Advertising Age puts it.

There are only three adult playdates set so far: in New York, London and Shanghai. Tickets are $20.

Meanwhile, Capri Sun has created an ad that mimics images from steamy romance stories to distract kids and tell parents that the drink company with iconic flexible packaging has reduced its sugar content by 40 percent.

In the past, Capri Sun has tried to break through to parents with viral posts replacing its juice with water, Ad Age notes.
