▸ The reading
interpretive · artSodium is soft enough to cut with a butter knife and violent enough to ignite the hydrogen it tears out of water. Split the difference and you get its two civic faces: the salt that preserved food across centuries, and the yellow streetlamp glow of every old motorway. A carbon-burning star's donation to the kitchen table.

Humphry Davy — isolated by electrolysis of molten NaOH · England · 1807
▸ Stellar origin
Carbon-carbon burning in massive starsOnce core temperature passes ~10⁹ K, two carbon nuclei fuse to produce sodium (or magnesium, neon, oxygen — branching depends on energy).
▸ Reactivity
Reacts violently with water; forms H₂ that ignites in airSoft enough to cut with a knife. Stored under mineral oil because moisture is its mortal enemy.
▸ Applications
- Table salt (NaCl) and food preservation
- Sodium-vapor streetlamps (yellow glow)
- Soap and detergents
- Sodium-ion grid-scale batteries
▸ Curiosity
Soft enough to cut with a butter knife, but drop it in water and you get a bang and a flame.
