Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.

A controlled demonstration by Wabash National of a tank trailer collapsing under vacuum, staged at an industry expo. The tank implodes as air is pulled out.

Footage of the 1985 world premiere of the Amiga 1000 at Lincoln Center. It shows demos such as multitasking and the bouncing ball, and Andy Warhol painting Debbie Harry live on the machine.

Amateur footage from 2014 of small airplanes being lifted and blown around during a microburst. It is a three-minute clip showing how violent the gusts can be.

A short Dyalog demonstration building Conway's Game of Life in a single line of APL, step by step. It shows how array operations replace loops.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

Techmoan demonstrates the Tefifon, a vintage German audio player that combines elements of record and tape with a grooved elastic loop. He shows how it works and plays it.

A short smartphone-recorded clip from a 2014 event in Paris where DeepMind CEO Demis Hassabis presents an AI learning to play old Atari games. The system learns from only the video signal and the score. Audio quality is poor.

A short animation reconstructing a planet's looping orbit using Ptolemy's epicycles and deferents, with the epicycles tracing out the face of Homer Simpson. It shows how enough circles can reproduce nearly any shape.

A two-minute demo of SmartKnob View, an open-source input knob built from a brushless gimbal motor, magnetic encoder and round LCD. Closed-loop torque control gives software-defined detents and end stops.

Bobby McFerrin uses audience participation at a World Science Festival event to demonstrate how instinctively people follow the pentatonic scale.

Smarter Every Day host Destin Sandlin tries to hover a helicopter and finds it very hard. The video shows how the constant coordinated corrections across several control axes feel at first and how learning makes them automatic.

A two-hour complete longplay of the 1993 MS-DOS puzzle game The Incredible Machine, in which players assemble Rube Goldberg contraptions to complete simple tasks.

A short demo from the Ishikawa Komuro Lab of a high-speed robot hand paired with a 1000fps vision system performing dexterous manipulation. It shows what very low-latency vision and actuation can do.

A demo of the Treventus ScanRobot 2.0 MDS, an automatic book scanner that digitizes very thick books up to 15 cm with gentle handling.

A short social experiment video in which people mimic the New York subway practice of workers pointing at signs and signals. It makes the point cheerfully.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

A brief demonstration of a railroad tank car imploding after a vacuum is pulled with its safety valves disabled.

Kitboga builds an elaborate automated phone maze with fake captchas, hold loops and absurd support to trap scammers for days. It also covers how this protects potential victims by wasting scammers' time.

SpaceX footage of the Grasshopper reusable rocket prototype flying 325 m before landing on its pad. It was the first test to use the full navigation sensor suite and closed-loop control for a precision landing.

An animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.

Mathematician singingbanana shows how he flipped ten heads in a row, with the full uncut video and answers to viewers' questions. The point is that unlikely events happen given enough attempts.

MKBHD drives a Tesla, a Mustang Mach-E and a gas car on a 1000-mile loop to compare total trip time and charging experience.
