Antifreeze

It's not just freezing but overheating that antifreeze prevents in car radiators. Take a closer look at how its chemicals change the boiling and freezing points of water.

Then explore how plants and animals have developed their own natural antifreeze proteins to protect them from winter's extreme cold.
