This Nov 2015 video, The Flat Side of Things 2, demonstrates the skills he’s developed since he began practicing at age 12. What’s flatland BMX?

Flatland is a freestyle BMX riding style performed on smooth flat surfaces that do not include any ramps, jumps, or grindrails. It is sometimes described as a form of artistic cycling with a blend of breakdancing… Tricks are performed by spinning and balancing on the bike in a variety of unexpected positions. Riders almost always use either knurled/grip taped aluminum or plastic pegs to stand on to manipulate the bike into even more imaginative positions.

Another video from August 2016: The Flat Side of Things 3.

And for a look at his skills in front of an audience, here’s Dandois at a VANS Jam in the city of Orange in December 2016:

In this video from Great Big Story, he explains, “The exposure times can vary from seconds to hours, and the idea is to use the light source as brushes or pencils.”

In Norway, lime bast fibre is also used to make rope. Filmmaker Silje Ensby captured how Norwegians have been making it for over a thousand years:

Ropemaker Ingunn Undrum and boatbuilding apprentice Dennis Bayer head out to harvest the bark of lime trees (linden tree), in the spring when the sap is rising.

The paper thin layers of bast are glued together, and need to soak for a long time in the sea to seperate. The water in the Hardanger fjord is cold even during summer, so the bark is soaking until fall, for 3-4 months.

Ropemaker Sarah Sjøgreen lays the bast rope, and makes a traditional carrying rope with three strands, for transporting the cut grass during hay making season. The bast is naturally water proof, and rots very slowly compared to other rope materials. This explains why it has been found intact in viking excavations dating back to the 800s.

There’s more info about the wild tiger’s 97% population decline in the last 100 years at panda.org:

Tigers not only protect the forest by maintaining ecological integrity, but also by bringing the highest levels of protection and investment to an area. Tigers are an “umbrella species” – meaning their conservation also conserves many other species in the same area. They are long-ranging and require vast amounts of habitat to survive; an adult male’s home range varies from 150 km2 – 1000 km2. Large areas of intact forest therefore must be preserved for tiger conservation…

Rather than focusing on “saving” tigers at a site or country level, Tx2 uses a strategic, long-term approach – working across entire landscapes and encouraging trans-boundary collaboration. This involves increasing protection where the tigers are currently, maintaining wildlife corridors and connectivity between areas and then boosting resources and protection for where tigers can be in the future, when their numbers have increased.

What important causes inspire you to create new stories, art, animation, design, inventions, or other kinds of ideas and solutions?

The Dodder Vine Sniffs Out Its Prey http://thekidshouldseethis.com/post/the-dodder-vine-sniffs-out-its-prey http://thekidshouldseethis.com/post/the-dodder-vine-sniffs-out-its-prey#comments Tue, 17 Jan 2017 06:11:24 +0000 http://thekidshouldseethis.com/?p=32921 From PBS Nature, watch as researchers Consuelo M. De Moraes and Mark Mesker conduct a series of experiments to find out if the dodder vine (Cuscuta pentagona), a parasitic plant that depends on a host plant to provide sustenance, can “sniff” out its plant prey.

“Plants obviously don’t have olfactory nerves that connect to a brain that interpret signals…but [some plants] do respond to pheromones, just as we do. Plants detect a volatile chemical in the air, and they convert this signal (albeit nerve-free) into a physiological response. Surely this could be considered olfaction.”

Above, botanist Daniel Chamovitz explains in this 2012 Krulwich Wonders article. Plus, there’s more from the researchers at NPR:

“It’s really amazing to watch this plant having this almost animal-like behavior,” [De Moraes] says. “It’s really very sophisticated and surprising.”

The study showed dodder also prefers certain odors. Given a choice of tomato or wheat, the dodder picks the tomato. Wheat may give off a chemical that repels the vines, which could mean good news for farmers.

“The fact that there are these repellant compounds suggest that you might be able to create a repellant or deterrent effect that would allow you to protect a crop against infestation,” says Mark Mesker.

Strong odors, more tomatoes, and more time lapse plant videos await, including Farm foods grow in time lapse, From seed to sapling – Time lapse of an oak tree, and What makes that fresh rain smell?

Can you solve the counterfeit coin riddle? http://thekidshouldseethis.com/post/can-you-solve-the-counterfeit-coin-riddle http://thekidshouldseethis.com/post/can-you-solve-the-counterfeit-coin-riddle#comments Tue, 17 Jan 2017 05:07:44 +0000 http://thekidshouldseethis.com/?p=32979 You’re currently locked in the dungeon by orders of the king, but as the realm’s greatest mathematician, you’ve been given a chance to free yourself: If you can identify a counterfeit coin, one fake coin in a group of twelve identical looking coins, you can earn your freedom.

Can you solve the counterfeit coin riddle? Don’t forget to hit pause and try to work out the problem before the solution is revealed! Then read more about this TED Ed lesson in logic by Jennifer Lu:

The counterfeit coin riddle is derived from the mathematics field of deduction, where conclusions are systematically drawn from the results of prior observations. This version of the classic riddle involves 12 coins, but popular variations can consist of 12 marbles or balls. Part of the appeal of this riddle is in the ease with which we can decrease or increase its complexity. A simple swapping of a few key words drastically alters the problem’s difficulty.

To make the problem simpler, for example, we can reduce the total number of coins to 9. To further simplify, we can reveal whether the counterfeit is lighter or heavier at the onset, as is shown here. For a harder version of the problem, start with 39 coins and four weighs.

Clearing snow from the cables on the Port Mann Bridge http://thekidshouldseethis.com/post/clearing-snow-from-the-cables-on-the-port-mann-bridge http://thekidshouldseethis.com/post/clearing-snow-from-the-cables-on-the-port-mann-bridge#comments Thu, 12 Jan 2017 16:04:14 +0000 http://thekidshouldseethis.com/?p=32934

The Port Mann Bridge is one of the largest cable stay suspension bridges in the world. To keep traffic flowing during winter storms, teams of Rope Access Technicians hang high over traffic to operate the bridge’s snow removal system.

Chain collars are fixed around all of the bridge’s 288 cables. The collars are attached to remotely operated hangers at the top of the bridge towers. When snow or ice builds up on the bridge cables, Snow and Ice Technicians drop collars to keep the cables clear.

Rope Access Technicians reload the collars at the end of each winter storm. Up to 30 collars are loaded on each cable.

These technicians with British Columbia’s Ministry of Transportation and Infrastructure work through cold, wet conditions high above the bridge deck to ensure the Port Mann Bridge stays open and safe to traffic.

The Paperfuge is a hand-spun, ultra low-cost, paper and string centrifuge that was inspired by the ancient whirligig toy. Wired shows us how it works.

Why is the paperfuge important? A standard centrifuge is usually a heavy, expensive, electricity-powered machine that spins around 20,000 revolutions per minute:

To test a person for diseases such as malaria, HIV, and tuberculosis, scientists spin samples of the patient’s blood, urine, or stool in a centrifuge. Thanks to centrifugal force, the spinning motion separates cells of different weights—such as pathogens in the blood—from the rest of the sample. Researchers can then look at the separated cells under the microscope to identify the disease.

In parts of the world that don’t have access to this kind of equipment, health workers might instead use the paperfuge. It can achieve 125,000 rpm and equivalent centrifugal forces of 30,000 g. Prakash explains, “Toys hide in them pretty profound physical phenomena that we just take for granted.” And these cost just 20 cents to make.

Madeline the Robot Tamer & Mimus http://thekidshouldseethis.com/post/madeline-the-robot-tamer-mimus http://thekidshouldseethis.com/post/madeline-the-robot-tamer-mimus#comments Wed, 11 Jan 2017 05:06:59 +0000 http://thekidshouldseethis.com/?p=32521 Inventor and designer Madeline Gannon developed a gesture-based robot communication software as an artist-in-residence at Pier 9 in San Francisco. She’s now developed something (someone?) new as the next step in her exploration of robot/human communications and companionship: Mimus.

Mimus is a giant industrial robot that’s curious about the world around her. Mimus sees the world differently than us – she uses sensors embedded in the ceiling above to see everyone around her simultaneously. Mimus can react and move quickly around her space to follow your actions and try to decipher your body language.

Madeline Gannon, who created Mimus, believes that the robots of the future shouldn’t replace us, but rather augment our own abilities and be designed with a focus on human interaction. Her goal in this exhibit is that the behavior and design are intuitive in a way that people who have never even seen a robot before will be able to immediately understand how to interact with Mimus.

You, too, can interact with Mimus at The Design Museum in London until April 23, 2017. The multidisciplinary exhibit, titled Fear and Love, explores subjects that provoke human anxieties and passions, including robots and automation.
