Deep engineering experiments: blast chillers, centrifuges, radar-absorbing panels, phase-change goop.
The husband-and-wife team doing genuinely deep engineering experiments: turning a household freezer into a high-speed blast chiller, building a giant centrifuge from scratch, testing microwave-blocking panels invisible to radar, sugar as a light source, and a black phase-change goop that beats ice. 1.2M subscribers, though uploads have slowed — last video about two months ago. The rigor is well above typical maker-channel level.
