During a failed attempt to discover gravity, Sir Isaac Newton fell face first into a snow bank while carrying a heap of delicious fruit—inadvertently discovering the health benefits of mixing squashed nutritious food with sub-Arctic cold. Today’s Groupon lets you replicate Newton's experiment under controlled conditions: for $3, you get a vitamin-packed 32-ounce smoothie (up to a $6.99 value) at Smoothie King in Carle Place.

Smoothie King's smoothies spin fresh fruit, natural juices, and special nutritional enhancers into more than 90 slurpable flavor and nutrient combinations, all of which focus on achieving one of seven nutritional goals. Try an antioxidant-rich Pomegranate Punch with pomegranate, bananas, blueberries, apple juice, soy protein, and Turbinado sweetener. Weight-conscious en-smuthiasts can trim down and float away with the Celestial Cherry High, packed with bananas, black cherry, papaya, Turbinado, and honey, and unpacked with fat.

Creative sippers can also customize any smoothie by adding enhancers, or “make it skinny” by cutting out the honey and Turbinado, for a more efficient route to good health than swimming laps in chocolate syrup. Smoothie King complements its smoothie selection with snacks and supplements to add variety to straw-focused diets.
