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.

Homemade Slushies
Do you enjoy ice-cold drinks? A slushy is about as close as you can get to liquid ice: colder than water, but more drinkable than ice! Using some common household items, a little bit of patience, and the help of science, you can make...

Practice Problem: Colligative Properties
What are colligative properties? They're properties of a solution, such as freezing point depression and boiling point elevation, which differ from the pure solvent. Let's do some calculations regarding these concepts!

Molality and Colligative Properties
Solute particles interfere with the physical processes a solution may undergo. These are known as the colligative processes of a solution. Ever wonder why we put salt on icy streets? Find out here!
