How about Gods gift to women/men? you could wrap a box up as a present and wear it with a huge tag on it that said To: Men/Women From: God
If you're going for something hottI'd def say go with a sexy story book/fairy tale characterLike little red riding hood, cinderella, alice in wonderlandsomething hott about twisting something like that! HAHA I'm going as snow white it looks like a dolls outfitIt's cute, and sexy but not revealing! Which is good! I'd say eBay it cuz those costumes are SO cheap on thereI just looked through all their listings until I found something I liked.
The magnetic field simply exerts a force which is all that a crane hook doesIt's an analagous situation - the crane hook does no work, it's the hoisting motor that does the work!
