Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!

What is the Circular Economy?
What if, when we make something new, we also consider how it can be unmade when it's no longer of use? Can the materials be separated and repurposed? Can some or all of it biodegrade? How do we keep it from polluting ...
Bayuble: Water-soluble fruit stickers
What do you do with the little fruit sticker from your apple? Do you put it in the trash or collect them? They can't be used again and "they're a major problem in composting facilities," so what can we do about this b...
Reconfigurable Ghostkube sculptures
Since we last saw Stockholm-based artist Erik Åberg's Ghostkube project, he's investigated the geometry, creativity, and organic qualities behind these interconnected cubes, building prototypes and exploring ways that...
An accidental toy inventor’s shapeshifting designs
What if we could make objects transform in the same way a flower unfolds from its bud? This is what designer, Harvard professor, and accidental toy inventor Chuck Hoberman is trying to figure out. His work, ranging fr...
Cooling without polluting: Two new green air conditioning innovations
The starry night sky seems remarkably distant from the topic of air conditioning, but it’s revolutionizing the field in quite an unexpected way. In this episode of "The Spark," watch how scientists from across the glo...
The Ocean Cleanup technology and challenges explained
The Great Pacific garbage patch in the northern Pacific ocean holds an estimated 1.8 trillion hard-to-see pieces of plastic that float around on or just below the water's surface. They're kept swirling in an area that...
Geothermal energy in Iceland
Iceland is a geothermal energy pioneer. Their unique geology, thanks to volcanism along a rift in the Eurasian tectonic plate and North American tectonic plate, provides a sustainable advantage: Heat from the ground. ...
The Solar Grandmothers of Ambakivao, Madagascar
Not having access to electricity, life in Ambakivao, Madagascar was dark. A group of grandmothers decided to change that, bringing light to their community by becoming the village’s first solar engineers. With the hel...
3D-printed structures that shape-shift with magnetic microparticles
These small, soft 3D-printed structures can shape-shift—expand, contract, wrinkle up, roll, and move about—thanks to the magnetic microparticles within their silicone-based rubber bodies. This is the latest iteration ...
These tiny origami robot transformers use magnetic fields to walk, roll, sail, and glide
This small cube can transform into a walking, wheeling, boating, or gliding bot with the help of origami exoskeletons that fold around it to create a new form and function. These are tiny shape-shifting robots from re...
Liquid Printed Pneumatics: 3D printing stretchy silicone structures
Imagine 3D printing a balloon of sorts, a stretchy material that can expand or contract with the air that's pumped into it. MIT’s Self-Assembly Laboratory, in collaboration with BMW, has developed a new way to print s...
Plastics 101: What is plastic and how is it made?
Once a completely natural product, much of today's plastic is man-made and largely dependent upon fossil fuels. From polymers to nurdles, learn how plastic is created and what we can do to slow the lasting repercussio...
Origami Changes Everything: Mass-producing an ancient art with 3D printing
Can origami, the art of folded paper, be used to 3D-print parts for our cars, pieces of clothing, art that we display, and other products? Can we build machines that can create patterns based on scans, and then cut, f...
Fungus: The Plastic of the Future
In 2014, Ecovative Designs was working to combine mycelium with local crop waste to make a compostable biomaterial for packaging, and continue to expand their efforts. One example: A collaboration with Netherlands-bas...
An innovative edible spoon, a smart alternative to plastic waste
Plastic cutlery has been around for years, widely considered the only choice for cheap, disposable cutlery. Knowing the threat plastic poses to our environment and health, Narayana Peesapaty created a tasty and nutrit...
What is public life?
In parks, at bus stops, on the sidewalk, in playgrounds, in street and farmers markets: These are just some of the public spaces where we can participate in our city's diverse and thriving public life, where people fr...
The Exhale Bionic Chandelier: Microorganism-filled ‘leaves’ that ‘breathe’
An air purifier, an art object, and a piece of lighting design all in one living, 'breathing' chandelier. This is London-based inventor and bioengineer Julian Melchiorri's Exhale Bionic Chandelier, a microorganism-fil...
Magnetic fields make this tiny robot roll, jump, swim, and wriggle
This very small elastic strip is a robot that can walk, roll, jump, swim, and wriggle like a worm. Infused with magnetic particles, it responds to the strength and direction of magnetic fields surrounding it. As scien...
