Authentic Thai Watermelon Smoothie

On a trip to Chiang Mai, Thailand, a few years back, I went to an "American Restaurant" which had on the menu a watermelon smoothie (but I think they called it a shake). I just now got around to figuring out the recipe, and I it's pretty spot on, taste wise. I make it on a weekly basis, it's that good. I hope you enjoy!
