Ben Krasnow of Applied Science demonstrates an X-ray fluorescence gun that measures chemical composition, tears it down, analyzes its failure, and discusses a new XRF technology appearing on eBay.

A family video in which kids write instructions for making a peanut butter and jelly sandwich and a parent follows them exactly as written, with comic results. It demonstrates how precise instructions must be.

Bob Nystrom shows his process for hand-drawing the diagrams in his book Crafting Interpreters, from pencil sketches to tracing and inking. It is a time-lapse of the whole illustration workflow.

Red Bull and the Dutch Drone Gods follow Max Verstappen's RB20 F1 car around Silverstone in a single FPV shot using a custom drone that accelerates to 300 km/h in about four seconds. The video also covers the year of development behind the drone.

A five-minute SuperMemo demo of incremental reading: importing a Wikipedia article on nutrition, extracting passages, making cloze deletions and finishing the item. It lists the keyboard shortcuts used.

The Explosions&Fire channel taste-tests the chloride salts of the alkali metals (lithium through cesium), plus some alkaline earth metals and ammonium. The presenter describes the flavors, and the results are more pleasant than expected.

NileRed tries to make a ring from pure purple gold, a gold-aluminium intermetallic that is brittle and hard to work with. The 53-minute video follows the chemistry and many failed attempts before he produces a finished ring.

LockPickingLawyer shows what happens when liquid gallium is applied to an aluminum Abus padlock, which weakens and breaks the metal. It is a short demonstration of gallium's effect on aluminum.

The Thought Emporium synthesizes chicken noodle soup from pure chemicals, following an original patent for artificial chicken flavor. The video explores how many chemicals it takes to make a convincing soup.

A short experiment dissolving the aluminum of a Coca-Cola can with drain cleaner to reveal the clear plastic film lining inside.

NileRed attempts to make transparent wood, inspired by an AvE video, by removing lignin and infiltrating the wood with resin. It is a long, detailed walkthrough of the chemistry and the practical difficulties.

A short clip of a ramen restaurant in Nagoya where robot arms cook the noodles. Human waiters serve the food.

carykh demonstrates a script that speeds up the silent parts of a video while leaving speech at normal speed, to condense lectures and similar footage. It later became the Jumpcutter tool.

Cody's Lab obtains pure heavy water (D2O) and drinks it as a taste test, reporting its flavor and feel. It is a short self-experiment.

LabCoatz uses mass spectrometry, with help from other science YouTubers, to reverse engineer the Coca-Cola flavor and builds a chemically-identical replica. The video walks through a year of work on the formula.

Epic Games shows how LED walls can provide both virtual backgrounds and real lighting, letting scenes be captured in camera in a single pass with Unreal Engine.

Mike Boyd takes up Smarter Every Day's challenge to learn to ride the Backwards Brain Bike, a bicycle whose steering is inverted, and rides 50 meters. It shows how hard it is to unlearn a motor skill.

Cody's Lab collects a sample of dust from the side of a highway and refines it to recover platinum-group metals deposited by catalytic converters. The video walks through the chemistry of separating and assaying the precious metals.

Project Farm tests six penetrating oils, including WD-40, PB Blaster, Liquid Wrench and an ATF and acetone mix, on rusted bolts. Liquid Wrench placed first and the homemade mix second.

California Superbike School demonstrates its 'No B.S.' bike, which has fixed handlebars so riders can only steer with body lean. It illustrates how little control that gives compared with countersteering.

Eon is a demoscene production by The Black Lotus, released at Revision 2019 and designed for an Amiga with OCS chipset, 512 kB chip and 512 kB fast memory. This is the party version, which has some known glitches.
