How NASA Reinvented The Wheel
Adults EngineeringA huge thanks to everyone at NASA Glenn Research Center for having us at the SLOPE Lab, showing their work on this indestructible tire, and helping with the science and animation.
rimitive Technology: Decarburization of iron and forging experiments
Adults EngineeringI took a brittle, high carbon/iron alloy (cast iron) made from local ore and used a decarburization method to reduce it's carbon content making it malleable and forged it flat by hammering.
Primitive Technology: Smelting Iron In Brick Furnaces
Adults EngineeringI made 3 furnaces from bricks using different configurations to test their effectiveness. The benefit of using bricks to make a furnace is that it's quicker, easier, re-useable and portable relative to a furnace constructed in-situ from clay.
Primitive Technology: Rock-Throwing Catapult (Trebuchet)
Adults EngineeringI built a trebuchet, a type of catapult that uses a counter weight to store gravitational potential energy which is then used to fire a projectile via a sling.

Primitive Technology: Improved Multi-Blade Blower
Adults EngineeringIn the 6 years since I developed the first forge blower I had made very few improvements to it's design.
Building the impossible: Golden Gate Bridge - Alex Gendler
Adults EngineeringExplore the construction of California’s Golden Gate Bridge, and dig into the engineering innovations that made the structure possible.
Paving machine
Adults EngineeringTiger-Stone is a Dutch made paving machine that uses gravity and an electric motor to print stone and brick roads. It's a six meter wide machine that is capable of laying 300 square meters of road a day.
How Does A Carburetor Work?
Adults EngineeringAir flows into the top of the carburetor from the car's air intake, passing through a filter that cleans it of debris..
How one design flaw almost toppled a skyscraper - Alex Gendler
Adults EngineeringDig into the unique engineering of New York City’s Citicorp Center tower, and the design flaw that threatened to topple it.
Building the world's largest (and most controversial) power plant - Alex Gendler
Adults EngineeringExplore the creation of China’s Three Gorges Dam, and find out how the hydroelectric plant generates its power.
How the world's longest underwater tunnel was built
Adults EngineeringDiscover how the English Channel Tunnel was built and the engineering challenges of building a 200 kilometer long tunnel underwater.
Primitive Technology: Brick Firing Kiln
Adults EngineeringPrimitive Technology: Brick Firing Kiln – building a brink firing kiln from scratch.
Why Don't We Have Water Powered Cars Yet?
Adults EngineeringToday we're dipping our toes into the engineering and physics behind water-powered cars!
Engineering with Origami
Adults EngineeringOrigami is inspiring a plethora of new engineering designs.
Flamethrower vs Aerogel
Adults EngineeringWe put aerogel to the test vs 'not-a-flamethrower', a huge 2000°C flame to a large fiberglass blanket infused with silica aerogel - formerly the lightest solid (that title is now held by graphene aerogel).
I Waterproofed Myself With Aerogel!
Adults EngineeringAerogel has extraordinary properties but it can be tough to work with. This video looks at modifying aerogels to take advantage of their unique characteristics.
Why Machines That Bend Are Better
Adults EngineeringCompliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great.
How does a whip break the sound barrier?
Adults EngineeringApril Jennifer Choi is a Mechanical Engineer and Professional Whip Artist from Peoria, IL. She has a Master's Degree in Computational Fluid Dynamics as well as several Guinness World Records in Whip Cracking.
How to Build a Dyson Sphere
Adults EngineeringIf humans want to expand into space, it will take us incredible amounts of energy. How do we do that?
