I thought of a few interesting ideas for this challenge, but my conscience made me keep it clean and decent.  Darn that conscience!!

My challenge to you is for you to show me the invisible.  

There is power in the air... although we cannot see it, we can feel it.  And so, I ask that you capture that power in your pictures.  

There is much that can fit into this challenge:  a flying bug, or bird, or a plane, or maybe superman... (hmm... he was part of one of my other challenge ideas too... ahem!) You could shoot flags, smoke, sails... or maybe even your brother (that's my bro Joe.  not quite sure what happened during uploading though... there seems to be a seam in the shot now?)  Owell...

Be creative, find or make wind, (make it, not break it) and have fun!!

Next challenger up... Jump1ok!!!
