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 fruit with sub-Arctic cold. Replicate Newton's experiment under controlled conditions with today's Groupon: for $3, you get one 32-ounce smoothie at Smoothie King (up to a $7 value). Choose between two locations: Chestnut Street and Market Street.
Smoothie King smoothies combine fresh fruit, natural juices, and special nutritional enhancers into more than 90 flavors, 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 sugar, to stay healthy and keep unruly, cell-sitting free radicals at bay. 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. Brain-freeze chasers can customize any smoothie by adding enhancers or “make it skinny” by cutting out the turbinado. Smoothie King complements its chilly selections with snacks, supplements, and healthy living advice, such as using a cell phone powered by good vibrations and marrying a vitamin tablet.
