How To Clear Icy Roads, With Science
Icy roads are a huge hazard, and typical methods of de-icing them can be pretty toxic to wildlife. Which is why researchers have been so fixated on finding better alternatives, from brine to pig pee.

Precipitation Reactions: Crash Course Chemistry
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this...
