I don't think its difficult, just time consuming. Make four scarecrows out of your old clothes and stuff with newspaper, sit them on a seat each leaving one spare empty in the middle. Place a laptop on each lap.
Take two broomsticks, tie their left hands to one stick and their right hand to the other. Sit on the central seat, tie your self on and rehearse your moves.
I'd probably need a drink or two at this stage, but good luck and don't forget to post the video when you've done.
