Daily Riddle — Jun 21, 2026

The trick here is that "changing its jacket" isn't clothing at all — it's the popcorn kernel's hard outer hull splitting open with that sharp pop everyone recognizes as the loud noise in question. That crack is the sound of the jacket giving way as heat builds inside. Then comes the sly bit of physics dressed up as poetry: once it bursts, the kernel puffs into a fluffy cloud many times its original size, so it clearly becomes larger. But moisture trapped inside turns to steam and escapes during that explosion, so the finished popcorn actually weighs less than the dense little kernel it started as. Bigger yet lighter feels like a contradiction until you remember it's mostly air now. Every clue maps perfectly onto the kitchen counter, which is exactly why the answer lands with such a satisfying, snackable click.
