The answer you are probably looking for is to bring an electrostatically charged object near it. Styrofoam cups often pick up an electrostatic charge when rubbing against each other or other objects. Depending on the charge on the cup, the charged object will either attract or repel the cup. Either way, it the cup will move.

Other ways to cause the cup to move without touching it, throwing an object at it, or blowing on it:

1. Use another object such as a pair of tongs to pick up the cup.

2. If you are in control of the setup, you can set the cup on another object, such as a napkin or a tablecloth and move the object on which the cup is resting. If the table is light enough, you might be able to shake or even lift the entire table, hence the cup.

3. If you are further restricted not to touch the cup even indirectly except through mutual contact with the floor, ask someone else to move the cup. A high-tech variation on this is to get a remote-controlled device to move the cup.

Edit: the idea of dropping a magnet into the cup and moving it with another magnet held under the table will work also, and also meets the conditions, even the condition that you not touch the cup indirectly. Building a dike on the table around the cup and then pouring water into it is also a messy but effective way to move the cup, as is firing a stream of liquid at it. Come to think of it, firing projectiles at the cup isn't quite the same thing as throwing them. Setting up a pendulum above the cup and letting the bob knock the cup over is yet another way. Looping a string around the top of the cup and pulling on the ends is a low-tech way to move the cup, but also comes under the heading of touching the cup indirectly. You can also push on the cup with a rod or stick.

For that matter, people avoid direct contact with hot objects all the time with towels, hot pot holders, and the like.

invert a previously dunked cup and place it over a water covered counter top. as the water beads inside the cup run off the wall of the cup, the weight of the cup lightens and floats over the water on the counter top. the cup will move if the counter top is slightly unlevel.

If it's light enough, you might be able to attract it to a charged object like a comb run vigorously through dry hair, or a glass rod rubbed with fur, or by extending a finger near it after you drag your feet on carpet to charge yourself.

Move what ever object it is on..this way you are not touching, blowing, or throwing an object at it.

magnets, vibrations or heat the air around it so that you create a convection current, basically artificial wind in this case. or put a hoover next to it. you said you cant blow, nothing bout suck :D

put a magnet inside it and use another magnet to attract for movement.

or even simpler

drop it

even even simpler

just leave it alone, since the world in spinning it's always in motion.

Put a magnet inside, then use another magnet to move it.

whoops...too late.

Wait trillions of years until all the protons in the cup decay.
