Indented excerpt from: ugzannin@sunybcs.UUCP (Adrian Zannin)

   Take 3-4 fairly good sized GLASS Christmas tree ornaments and fill them 
   with some kind of paint (I like black oil-based house paint).  Then seal 
   the tops of them with children's Play-doh or something similar. [...]
   Then, when some jerk in a 18-wheeler pulls up behind you like that, first
   be polite and ask him to move back by waving out the window with your hand.
   If he doesn't back off, simply reach over and pick up one of the ornaments,
   hold it at arm's length out the window, and throw it straight up.  I don't
   know of too many people who can see through house paint!  It really works,
   although the consequences can be quite drastic...

I don't quite see how this works.  You see, if you throw the ornament
straight up, it is still traveling at the same speed as your car.
So what exactly makes it slow down in mid space and wait for the truck
behind you?  Of course air resistance will help this, but this will be
minimal on a smooth object like a ball.  Further, gravity will also be
working hard to pull it down.
