I showed this to my wife who quickly recognized it as an essential part of her life:
Spray it, don’t squeeze it! Stem is designed to allow a cook to spray juice directly from a citrus fruit. No longer do you have to cut and squeeze your fruit to get the juice out like a common cook. With only one finger you can now spray citrus juice on your favorite foods evenly. Let Stem add a little zest in your kitchen and on your food!
