Air Cannon
You can build your own "vortex generator" with just a few simple, household materials.  The PBS' Air Cannon shows how to build an air cannon from a plastic bag, bucket, and rubber bands--just be sure to have an adult working with you.  There is even a poll so that you can report your results and compare them with what others found.
