An 11-minute guided Wim Hof breathing session built around an expanding and contracting bubble to pace the breath. Wim breathes along with the viewer over ambient sound.

Wim Hof guides viewers step by step through his breathing method, with some explanation of the science he cites behind it. It stresses learning from the source and avoiding unsafe settings.

Ben Krasnow of Applied Science shows how to make and test YBCO high-temperature superconductor with a kiln and eBay chemicals. He demonstrates flux pinning and shows a close-up of the crystal structure.

Dr. Mark Cucuzzella of the Natural Running Center gives a short instructional video on natural running form. It describes the principles of good technique, including barefoot-style mechanics.

A 1993 Yoga Works video of the Ashtanga Yoga Primary Series led by Sri K. Pattabhi Jois, with senior students demonstrating. The class is filmed in classic style from the back of the room.

Ben Krasnow of Applied Science explains how electrophoretic e-paper displays work and how he modified the driver firmware and waveform lookup tables of a 4.2-inch panel to reach roughly 3Hz partial refresh. It covers the tweakable constants in the refresh process and touches on colored e-ink microcapsules.

Applied Science builds a replica Apollo DSKY using an electroluminescent driver circuit and screen-printed conductive ink, with source and PCB files published.

Ben Krasnow of Applied Science shows how to make small batches of specialty glass with minimal equipment, including designing and making photochromic glass. He covers ingredients, melting and the challenges involved.

Matt Risinger demonstrates a blower door test on a house, using a fan to measure air leakage and find where air gets in and out. It shows how the test reveals the quality of the build.
