A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

It's quite handy that ice floats for summer drinks (lemmy.world)

Ice floating and cooling the upper part of a drink should start a natural convection type cycle which cools the whole drink. If the ice sank, you'd have a very warm surface layer. Never thought about this with focus before 😅

It’s even more important than your drink! The fact that I’ve floats is what allows ice to act as an insulator on top of frozen lakes and oceans. If it sank, liquid water would take its place and freeze. After a while the whole body of water would be frozen.
