Mini fans at the Superbowl

I was invited over to my friend's place for the Superbowl.  Since the Patriots weren't playing, I wasn't too interested and hadn't even planned anywhere in particular for watching the game.  After my friend enticed with me with tacos, I couldn't refuse.  Wine in hand and fuzzy slippers in my bag, I soon found myself watching my friend's roommate slice and dice up a delicious guacamole and salsa verde.  After gorging on two or three tacos and about a pound of avacodo, the half time show arrived.

Coldplay came on first, and stunk.  That's all I'm going to say for him(them?).  Next, Beyonce graced us with her presence, being ever wonderful and sassy.  Or was it Sasha Fierce?  I don't know.  Third to pop up from behind his piano was little Bruno Mars.  He was undoubtedly the best performer.  He is a greater performer because you can easily watch his love of the performance shine through.  It reminds me much of Michael Jackson.  They both radiate with their joy of dancing, singing, and performing.  It is abundantly clear and visible on their faces and in the movement of their bodies, every moment!

Anyway, the performance was wrapping up and all three artists came together to belt out the last few moments of the song.  Everything seemed to fade away on the TV screen, except for one thing.  Hair.

Beyonce's hair was moving, nay, flowing.  No one else seemed to have a fan or breeze pointed at them, but here she was, locks waving away as if they were waving to a crowd from a parade float.
What the heck?  Does she have mini fans attached to her shoulders?  I can't figure it out.  Well played, Sasha Fierce.  Your hair is fierce and flowing.
