Most of today's crop is low-effort Shorts content — pencil-lead "soldering irons," recycled clickbait about salt on iron tips, and hashtag spam. This stained glass dragonfly video is the standout because it shows an actual soldering skill applied to a real project, not a 15-second trick.

Stained glass soldering is a genuinely useful cross-training exercise for electronics folks. You're working with lead-tin solder on copper foil, managing a much larger thermal mass than a PCB pad, and building continuous smooth beads instead of discrete joints. The technique — flux application, tip angle, feed rate, and heat control — translates directly to skills like drag soldering on fine-pitch ICs and building up bridges on connector pins.

Watching a craftsperson lay down clean, consistent solder beads at length is one of the best ways to internalize what "good flow" looks and sounds like. The satisfying sizzle of flux flashing off is the same feedback loop you want when tinning wires or reflowing a joint. At 10.5" wide, the dragonfly gives enough runtime to actually study the motion.
