Instant Freeze - Soda Ice

Here is a fun display that will help your physical science fanatics understand freezing points and crystal formation. Use rock salt, sparkling water, and ice to create a -10¡C bath.

Make sure to visit Steve Spangler's website to learn more about exact amounts for the ice bath and tips for explaining the concepts.
