Here's something that might surprise you:

Honey never spoils. Archaeologists have found pots of honey in ancient Egyptian tombs—over 3,000 years old—that were still perfectly edible. Its low moisture content and acidic pH make it inhospitable to bacteria.

But of course, I'm guessing at what you don't know. To give you something genuinely new, it'd help to know a bit about you—your field, interests, or what you've already explored.

In the meantime, here are a few more from different domains:

  • Octopuses have three hearts and blue blood (copper-based rather than iron-based).
  • Bananas are radioactive—they contain potassium-40, an isotope. You'd need to eat millions at once for it to be dangerous, though.
  • The Eiffel Tower grows in summer—heat causes the iron to expand, making it up to 15 cm taller.
  • Wombats produce cube-shaped poop, which they use to mark territory; the cubes don't roll away.

Want me to go deeper on any of these, or aim at a specific subject you're curious about?
