A mesmerizing pendulum wave demonstration with 16 bowling balls in a North Carolina forest

A mesmerizing pendulum wave demonstration with 16 bowling balls in a North Carolina forest video physics math kinetic sculpture

If you’ve ever been to a science museum or taken a physics class, you’ve probably encountered an example of a pendulum wave. This video shows a large-scale pendulum wave contraption built on private property in the mountains of North Carolina, near Burnsville. The mechanism relies on 16 precisely hung bowling balls on a wooden frame that swing in hypnotic patterns for a cycle of about 2 minute and 40 seconds. Via Maria Ikenberry who filmed the clip:

The length of time it takes a ball to swing back and forth one time to return to its starting position is dependent on the length of the pendulum, not the mass of the ball. A longer pendulum will take longer to complete one cycle than a shorter pendulum. The lengths of the pendula in this demonstration are all different and were calculated so that in about 2:40, the balls all return to the same position at the same time – in that 2:40, the longest pendulum (in front) will oscillate (or go back and forth) 50 times, the next will oscillate 51 times, and on to the last of the 16 pendula which will oscillate 65 times.

Because the piece is outdoors, a number of factors prevent the balls from precisely lining up at the end, but it’s still easy to get the idea. In a perfectly controlled environment you get something like this.

Update: The pendulum was built by Appalachian State University teacher and artist Jeff Goodman.

Artist Kevin Weir Creates Ghostly Animated GIFs Using Archival Photos from the Library of Congress

Starting this month Verizon FiOS customers can get upload speeds every bit as fast as their download speeds. Since that means faster, easier sharing of high-res illustrations, designs, and photos, FiOS is sponsoring a series of posts on Colossal to help us commission and share these super hi-res animated GIFs from some of the most amazing artists we could find.

Art director and designer Kevin Weir uses historical black and white photographs forgotten to time as the basis for his quirky—and slightly disturbing—animated GIFs. His path to online GIF superstardom began when he was in high school. He tells us that “my parents’ boss bought me a copy of Photoshop and I decided I wanted to be some kind of designer.” Having mastered the software, he found himself five years later “making black and white GIFs as a way to occupy myself during the downtime of an internship I had during grad school.” He shared the images on his Tumblr, Flux Machine where they quickly went viral.

Weir makes use of photographs he finds in the Library of Congress online archive, and is deeply drawn to what he calls “unknowable places and persons,” images with little connection to present day that he can use as blank canvas for his weird ideas. Perhaps it’s the nature of his imagination, or maybe a result of the medium’s limited frames of animation to communicate anything too serious, but despite the creepiness factor, it’s hard to not to smile at the absurdity of his ideas.

Weir is now an art director at Droga5 in NYC, he also also animates music videos and sassy birds.

Yes, it’s that time of year again for the world’s largest flower parade, Corso Zundert in the Netherlands! Located in the small town of Zundert at the Belgian border, the annual parade features 20 giant floats created by various districts within the city. To encourage a wide breadth of creativity the parade never has a theme, leaving teams free to design whatever they want as long as the floats fit the within 20 x 10 meters and are completely adorned with dahlia flowers.

This year the parade saw everything from a deconstructed 737 airliner to a guitar-playing cephalopod, with the first place prize awarded to the brawny flexing horse float, Horsepower.

If you want to explore a bit more, there are more photos of the 2014 event courtesy Omroep Brabant, and you can also see our Corso Zundert coverage in 2013 and beyond.

Woodworker Creates Detailed Stop-Motion Films of his Process

Woodworker Creates Detailed Stop Motion Films of his Process wood stop motion animation

Designer and woodworker Frank Howarth has a passion for building things with his hands, he makes everything from shelves and chairs to toys and tables. But there’s one thing he might be even more passionate about: showing people how he does it on his YouTube channel. In some of his most popular films, the Howarth removes himself completely to create stop-motion animations with thousands of photos, where the objects appear to build themselves. In the two shown here he builds a trio of bookshelves and a lawn chair. If you liked this, don’t miss the Triumph Spitfire clip. (via The Awesomer)

First a Boeing 747, and now an industrial complex on a Vancover island; it seems no canvas is too large for Brazilian graffiti artists Os Gemeos who were invited to the Vancouver Biennale to turn six multi-story silos on Granville Island into their trademark ‘Giants.’ The murals on the 70-foot towers are now the largest paintings ever attempted by the pair, an astounding feat considering Os Gemeos completely donated a month of their time to create the non-profit art project. An Indiegogo fundraising campaign to recoup costs associated with painting the silos has been extremely successful. You can see more over on Arrested Motion.

Paper artist and graphic designer Yulia Brodskaya first began to experiment with various ways to illustrate using paper about six years ago. In the time since she’s become a master at quilling and other sculptural techniques involving paper, landing high-profile jobs working on paper projects for fashion designer Issey Miyake, Godiva chocolates, and even Paramount films.

In her own time, Brodskaya often returns to an exploration of aging and older people, inspired in part due to fear of her own mortality, but also in an attempt to portray aging people with dignity by rendering them in brilliant color, or by showcasing their interests. There’s also an added bonus: quilled paper is an excellent medium for creating wrinkles.

You can see much more over on her website, and Brodskaya’s work appears in the new book Paper Cut: An Exploration Into the Contemporary World of Papercraft Art and Illustration.

Timelapse of the Amish raising a giant barn in under 10 hours timelapse Ohio barns architecture Amish

Ohio resident Scott Miller shot this timelapse video earlier this year of dozens of Amish men raising a barn. The entire construction cycle takes place between 7am and 5pm—with at least an hour for lunch—and yet the bulk of the work is done by the end of the day. Amazing to see how incredibly precise the entire endeavor is. (via Sploid)
