Caesium

Golden, liquid on a warm day, and the most reactive metal there is.

Only 0.5% of people are Caesium. (estimated)

If you're Caesium

You are warm, golden and completely unpredictable. You explode at the smallest provocation and everyone forgives you because you're beautiful about it.

Caesium is pale gold, melts at 28 °C, explodes on contact with water, and defines the second in every atomic clock.

How to get along with Caesium

Do

  • Enjoy the gold and keep a fire blanket handy.
  • Give them precision work; they define the second.
  • Forgive fast; they explode, they don't sulk.

Don't

  • Don't introduce them to water, sudden bad news or your ex.
  • Don't expect room-temperature calm; they melt at 28 degrees.

When it goes wrong: Bang. Then a shy golden apology. Accept it; it's real.
