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. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Alumina (aluminum oxide) is what you are extracting from aluminum ore and it's tough as fuck, which is why it's easier to dissolve the rest of the stuff around it first.

Oxygen is mainly that other "junk" you have to separate with electricity. While the smelters only run at 4.5 volts (per cell), they have to push about 300kA to get the stuff up to ~950°C which breaks its chemical bond.

You probably have never even touched pure aluminum before. Aluminum and oxygen react so quick, all we typically ever see and touch is a alumina shell.
