Glow-in-the-Dark Paths Come to Singapore

Glow-in-the-dark materials are no longer for toys. Photoluminescence can help cities feel safer at night, whether it’s part of a mural, a bike lane, or a highway. Glow-in-the-dark paths have been tested in several European cities (the above is a Van Gogh-inspired bike path by the Dutch artist Daan Roosegaarde) and in Texas, but now, the technology may be coming to Singapore. The city-state is currently developing a 15-mile greenway called the Rail Corridor, and it now has a glow-in-the-dark path, as Mashable reports.

The 328-foot stretch of glowing path is part of a test of multiple surface materials that might eventually be used throughout the park, depending on public opinion. In addition to the strontium aluminate-beaded path that glows at night, there are also three other 328-foot stretches of the path that are paved with fine gravel, cement aggregate, and part-grass/part-gravel. The glow-in-the-dark material embedded in the walkway absorbs UV light from the sun during the day and can emit light for up to eight hours once the sun goes down.

However, in practice, glow-in-the-dark paths can be less dazzling than they seem. Mashable’s reporter called the glowing effect on Singapore’s path “disappointingly feeble.” In 2014, a glowing highway-markings pilot by Studio Roosegaarde in the Netherlands revealed that the first road markings faded after exposure to heavy rains. When it comes to glowing roads, the renderings tend to look better than the actual result, and there are still kinks to work out. (The studio worked the issue out eventually.) While a person walking or biking down Singapore’s glowing path might be able to tell that they were staying on the path better than if they were fumbling along dark pavement, it’s not the equivalent of a streetlight, for sure.

The trial paths opened to the public on July 12. The government is still gathering survey responses on people’s reactions to the different surfaces to determine how to proceed with the rest of the development. If the glow-in-the-dark path proves popular with visitors, the material could eventually spread to all the paths throughout the Rail Corridor. You can see what the glowing path looks like in action in the video below from The Straits Times.

Watch 32,000 Dominos Fall in an Extremely Satisfying Way

Lily Hevesh, known as Hevesh5 on YouTube, has achieved viral fame many times over with her ambitious domino videos. She's shown us dominos falling up a flight of stairs, dominoes toppling in a three-part spiral, and dominos collapsing in a continuous chain of record-breaking length. To make the video below, she collaborated with six fellow domino artists and set up an elaborate, freestyle design that leads to a domino fall that's incredibly satisfying to watch.

According to the video's description, this was the biggest project Hevesh and her collaborators built during a domino event she hosted earlier in 2019. The artists—which in addition to Hevesh5, included YouTube creators NC Domino, StickTrickDominoDude, Chris Wright, Jaytar42, jackofallspades98, and SmileyPeaceFun—gave themselves three-and-a-half days to set up 32,000 dominos using the most oddly satisfying domino tricks they knew.

Hevesh writes in the video description: "Everything in this setup (besides one field) was freestyled so we did not draw out a detailed floor plan. All we had was a list of satisfying domino project ideas that we built and connected on the spot."

In less than four minutes, the video showcases pyramids, spirals, and artistic patterns, all made from toppling plastic bricks. Whether or not you can name all the domino tricks that are featured, seeing them in action is mesmerizing. You can watch the full video below, and then subscribe to Hevesh5 for more domino creations.

What's the Difference Between Art Deco and Art Nouveau?

The Quick Trick: It all comes down to "flowery"vs. "streamlined." Art Nouveau is the decorative one. Art Deco is sleeker.

The Explanation: Both the Art Nouveau and Art Deco movements emerged as reactions to major world events; the Industrial Revolution and World War I, respectively. While both embraced modernist elements, they're easy to distinguish if you know what to look for.

Art Nouveau (it means "new art," but you probably figured that out) reigned from roughly 1880 until just before World War I. Art Nouveau embraced Europe's new industrial aesthetic rather than challenging it. It features naturalistic but stylized forms, often combined with more geometric shapes, particularly arcs, parabolas, and semicircles (think of the paintings of Gustav Klimt, or the arches of the Eiffel Tower). The movement brought in natural forms that had often been overlooked, like insects, weeds, and even mythical faeries, as evidenced by Lalique jewelry or Tiffany lamps. The black and gold robe Kate Winslet doffs in the erotic portrait session scene in Titanic is quintessentially Art Nouveau.

Art Deco, on the other hand, emerged after World War I. In fact, the deprivations of the Great War years gave way to a whole new opulence and extravagance that defined the Jazz Age and the Art Deco aesthetic. The movement took its name from the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes, which was held in France. The style was prevalent from the 1920s until roughly the start of World War II and is characterized by streamlined and geometric shapes. It also utilized modern materials like chrome, stainless steel, and inlaid wood. If Art Deco dabbled with natural materials, they tended to be graphic or textural, like zebra skin or jagged fern leaves. As a result, Deco featured bold shapes like sunbursts and zigzags and broad curves. In fact, if you check out the spire of the Chrysler Building, the hotels of Miami's South Beach, or the "coffin nose" of a 1935 Cord Model 810, you'll be staring at the very definition of Deco.

Of course, you don't have to go outdoors if you're looking for Deco. Furniture from the period—like the black leather and chrome chaise longue by Le Corbusier or the Barcelona chair by Bauhaus giant Ludwig Mies van der Rohe—is still coveted by design aficionados and can be found in finer hotel lobbies everywhere.
