I'm with KevinP73--real but not at 60-100mph. If you stop the clip and move frame by frame during the shot from behind the armor, you can see the watermelon (or at least a large portion of it) right where her head would be. The next frame shows pieces off to the left and the girl behind her reacting. I think the watermelon may already have been broken as it flung back but still, I think it's real. (It may take a few tries to stop frame and get the shot but when you do, try zooming in--it sure looks like a watermelon to me.)
