Primitive Technology: Water Bellows smelt
AdultsCreativityEducationNature...I tested the water bellows with a smelt and it produced a small amount of iron from the ore. The concept has a lot of potential but is having some issues.
Primitive Technology: Water Bellows (uses water instead of leather)
AdultsConstructionCreativityEducation...I built a Water Bellows. It’s an upside-down clay pot with an inlet valve and an outlet spout. The inlet valve is simply a hole in the pot with a leaf plastered to the inside with wet clay so that it forms a one-way flap valve.
Why It Was Almost Impossible to Make the Blue LED
AdultsHistoryScienceTechnology...The blue LED was supposed to be impossible—until a young engineer proposed a moonshot idea.
Primitive Technology: Downdraft Kiln
AdultsCreativityEnvironmentLife...A Phoenix kiln is a type of downdraft kiln where the firebox is below the ware chamber.
Primitive Technology: Wood Ash Insulated Furnace
AdultsConstructionCreativityNature...I made a furnace insulated with wood ash to smelt iron in. Furnace insulation stops heat being lost from the walls of a furnace and so increases the heat within the furnace.
Primitive Technology: New Brick Kiln Design
AdultsCreativityEducationNature...I cleared an area as a workspace for making bricks, trialed a new source of clay for brick making and tested a new kiln variant that uses fewer bricks than the previous design.
How NASA Reinvented The Wheel
AdultsConstructionCreativityScience...A 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
AdultsConstructionCreativityLife...I 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
AdultsEducationLifeNature...I 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)
AdultsCreativityEducationNature...I 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.

Building the impossible: Golden Gate Bridge - Alex Gendler
AdultsConstructionHistoryHuman...Explore the construction of California’s Golden Gate Bridge, and dig into the engineering innovations that made the structure possible.
Paving machine
AdultsConstructionProductivityEngineering...Tiger-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?
AdultsConstructionCreativityPhysics...Air 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
AdultsCitiesConstructionHistory...Dig 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
AdultsConstructionDesignIndustry...Explore the creation of China’s Three Gorges Dam, and find out how the hydroelectric plant generates its power.
