I love Gravity

gravity long and windy2

Gravity is one of my favorite physics topics, mainly because it is the one which is most taken for granted. If I were to drop a ball and it magically would go flying toward the wall, people would shit themselves in wonder.  But if I drop a ball and it falls to the ground, people shrug their shoulders unimpressed.  Yet it is still freakin' crazy!  The ball is moving around without anything touching it yet somehow we're all trained to believe that's not a big deal.

I like the Sun Gravi-Tee for a few reasons: 1) it's cool looking, 2) it doesn't have a logo or brand covered all over it, 3) it includes blue and orange which are two meaningful colors to me, 4) it has a built-in pickup line "If you're wondering why you're finding me so attractive, it's just the shirt...", 5) if I can teach physics through clothing, that's pretty dope.
