Here's another Pinterest find (my super friend found and shared with me)!
I had no idea that a standard wide-mouthed mason jar will fit a standard blender attachment. But it does! So now, my smoothies require no blender and cup to wash, just the one jar. Yay!
Bonus!! Since we all like different flavors in our family, our milkshake nights will be way easier!!
Everyone can prepare his/her own, attach the screw-on blade, and blend.
Remove blade, and drink from the jar. I've tried all sizes of my jars here at home, and they all fit!
