Chainmaille WeavingI bought a sandwich bag of little metal rings at a market and got quietly furious to learn that whether they click together is decided, entirely, by long division.
Catch the Egg, Not the Trampoline: Landing the Toss
Diabolo Gyroscopic String AccelerationTurns out a wooden ball on a string fixed the toss I'd been failing for a week: a taut string is a trampoline, so catch the diabolo like an egg — sink the knees and give.

When a Bag of Rings Becomes One Object
Union-Find (Disjoint Sets) 🔗 Chainmaille WeavingA chainmaille sheet is only an object if every ring connects to every other — the same question disjoint-set forests were built to answer.
games
🎮 Spin & Toss Pump a diabolo's string to build gyroscopic spin, launch it skyward, and tap the instant it drops back onto the string. More spin means a wider, more forgiving catch.
🎮 Trace the Weave Thread each new chainmaille ring by drawing one stroke through the glowing gold holes in order while dodging the red ones. Beat the patience meter to complete the day's weave.
