Primitive Technology: 2.5 m Natural draft furnace experiment
AdultsEngineeringExperimentsTechnologyI built a 2.5 m tall furnace to see if it could get hot enough to smelt iron by natural draft alone. Such furnaces work by the stack effect where the tall furnace causes negative pressure inducing an air flow from the base of the furnace and out the top.
Primitive Technology: Charcoal retort experiment
AdultsExperimentsTechnologyI tested a charcoal retort based on the Hookway retort method using only primitive materials.
People said this experiment was impossible, so I tried it
AdultsEducationScienceExperimentsA massive thank you to everyone at Goldschmidt for making this possible. With special thanks to Dr. Axel Hoeschen, Christof Gassmann and Claudia Koch.
Primitive Technology: One-Way Blower Iron Smelt & Forging Experiment
AdultsConstructionCreativityEducationScienceExperimentsI tested the one-way spinning blower in an iron smelt and it is more effective than the previous both way spinning blower.

Primitive Technology: Crab and Fish Trap
AdultsConstructionCreativityEducationDIYExperimentsSurvivalI made a fish trap from cane and tested it over the course of a year catching various aquatic animals.
Primitive Technology: Brick and Charcoal Production
AdultsConstructionCreativityEducationDIYExperimentsIn this video I use the thatched hut to fire bricks and make charcoal in for the first time.
Primitive Technology: Roasted Ore and Shell Flux Smelt
AdultsCreativityLifeNatureScienceExperimentsI tested 2 ways of improving iron smelts by treating the ore, roasting the ore and using snail shells as a flux. Then finally I recycled old slag to see if it would produce any more iron.
3 Ways Of Seeing Invisible Air Flow
AdultsEducationScienceExperimentsIn this lab, they use different flow visualization techniques to help detect contraband, residues, and develop trace particle detection methods.
The Future of Machines That Move like Animals | Robert Katzschmann | TED
AdultsExperimentsLifeTechnologyNatureImagine a boat that propels by moving its "tail" from side to side, just like a fish. That's the kind of machine that TED Fellow Robert Katzschmann's lab builds: soft-bodied robots that imitate natural movements with artificial, silent muscles.
Making Liquid Nitrogen From Scratch!
AdultsEducationPhysicsScienceExperimentsI used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew.

How to Make an Elephant Explode with Science - The Size of Life 2
AdultsAnimalsGeneticsScienceBiologyExperimentsLife on this planet is based on cells. Cells do vary in size. But they are pretty similar in their dimensions across all species. A blue whale doesn't have bigger cells than a hummingbird, just a lot more of them.
