Here's a great how-to on building a "liquid fueled" rocket using little more than a fat Sharpie marker, a can of compressed air, and a few more supplies found down on the Cube Farm. The resulting rocket can fly up to 75 feet!
But hey there, John Glenn of the IT Department, BE CAREFUL! This is actually a project you don't want to take lightly. Launch it outdoors, wear safety goggles, don't "burn" yourself on the compressed air (it's *very* cold). Generally, be smart, and use common sense whenever dealing with any type of projectile and components under pressure.
What you need:
A Sharpie
Canned Air
Electrical Tape (Substitute Packing Tape)
Ball Point Pen
Rubber Band
Bottle Cap
Leatherman
TIP: On the Comments to this Instructable, a maker suggests cutting off the bell-shaped end of another Sharpie and adding it to the thrust end of your rocket to form a De Laval nozzle for better thrust performance.
See the full Instructable for more details.

Very cool (literally). However, let me just add a specification. I learned from experience that a Bic ballpoint pen's tube is too narrow for the duster's hose to fit into. Papermate brand pens, however, are the perfect diameter to form the rocket's nozzle.
