How Many Balloons? - weigh the things you'd float, with honest ranges

A playful balloon-lift thought experiment. Free in the browser: list things to float (name, your own weight, a note), pick a balloon kind, and see how many party balloons it would take - low, likely and high - drawn as a balloon cluster, with each thing's weight as a whisker on a log scale, counts for four balloon kinds (lift figures are estimates) and exports (Markdown, CSV, JSON). One metered task estimates every unweighed thing as low, likely and high grams anchored on base rates, keeps your own weights, names the thing to weigh first, and gives a verdict (a bouquet, an armful, a cloud, grounded) and a flight note; the page re-checks every reply. People and animals are never counted. Built on @tjboudreaux/thinking-probabilistic.
