Tested explains how Apple's Touch ID recognizes fingerprints, then tries to defeat it using fake fingers and prints, retracing methods claimed by a German computer club.

Builder Matt Risinger freezes water-filled copper and PEX piping capped with SharkBite fittings to see which survives. The video compares how each pipe type handles freezing.

Footage of an unmanned Apollo boilerplate capsule launched on a Little Joe II booster to test the launch escape system. The booster went out of control and broke up, but the escape system worked and the capsule was recovered undamaged.

RMC tests running a classic 68k Mac environment through emulation on an accelerated Amiga and compares it to real Mac hardware. It explores whether an Amiga can be the fastest classic Mac.
