Alexa-based smart dumbbells can adjust weights via voice command. “The Spine Collector” scams book editors for manuscript copies of forthcoming books, for seemingly no reason whatsoever. QR code-based parking meter scams. An electronic mask can detect leaks. A liquid based bubble clock. How did people clear roads before the snowplow? Walmart’s special “Pain Box” DVD edition of “Dune.” All that and more in WhatTheyThink’s Wordle-winning miscellany.
