Cucumber Celery Cooler Smoothie

Today I ventured out to make a fruit-free smoothie. I'll warn you, this is an acquired taste. I would recommend weening the fruit in your smoothies to prepare your taste buds. I think this smoothie is refreshing but my hubby thinks otherwise :). Are your taste buds ready for an adventure?

2 cups water
1 celery stalk
1/2 cucumber
1/2 avocado
2 cups spinach
5 sprigs cilantro
2 kale leaves
Ice

*If you must add fruit to improve the flavor, I recommend a banana.
