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.
Primitive Technology: One-Way Blower Iron Smelt & Forging Experiment
AdultsConstructionCreativityNature...I tested the one-way spinning blower in an iron smelt and it is more effective than the previous both way spinning blower.
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: 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.
Explaining concrete while getting buried in it
AdultsConstructionHistoryScience...Concrete = cement + sand + gravel. Cement is the most important man-made material on Earth.
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: 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.
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..
Primitive Technology: Brick Firing Kiln
AdultsCreativityMediaNature...Primitive Technology: Brick Firing Kiln – building a brink firing kiln from scratch.
Why Don't We Have Water Powered Cars Yet?
AdultsCreativityIndustryScience...Today we're dipping our toes into the engineering and physics behind water-powered cars!
Engineering with Origami
AdultsConstructionCreativityScience...Origami is inspiring a plethora of new engineering designs.
