  1. Did you take this picture? It has a warm, satisfying glow that makes me want to touch it.

  3. Melting point capillary, add one small crystal of elemental iodine, flame seal the open end. Irradiate the dilute gas phase ( |<- ) with the fat argon laser green line or a green laser pointer. YOWSA!

    Curiously, evacuating the capillary before sealing leds to inferior results.
