You can... put a mason jar on your blender!! Yes. You can. Well, if it fits on your blender. A lot of mason jars are different sizes. And a lot of blenders are weird. If you have a blender like mine, and a cute lil jar like mine, then you can make awesome single-serving smoothies. It's so cool. (there's a video at the bottom if you don't believe me!)

Be careful when trying this... we used all fresh fruit and I'm not sure what would happen with some ice. AKA... try at your own risk. Mason jars probably aren't as strong as blender glass.
