Sour Science

When life gives you lemons, experiment! Follow along as you make a colorful lemonade, learn how to make it fizzy, and turn it into a yummy frozen sorbet while learning the scientific principles behind each transformation.  We'll also squeeze in a demonstration on how lemons can be turned into a battery.
