May the Mass x Acceleration Be With You
Every week on the day after Monday, we're releasing new shirt designs in the mental_floss store. Today, we're celebrating May 4—aka Star Wars Day—a little early with a tee about the formula behind The Force.
And that's not all we have for Star Wars Day: You can find tons more stuff for the Jedi in your life over in the mental_floss store.
