This is a fun and quick project for physics students at all levels. After you perform the demos in the teacher instructions (all with easily found items like balloons), assign your students this rubric to do a demonstration of their own. Each demo will take 1-2 minutes in class so you can run through an entire class in a period or block and students will see lots of variations on electrostatics.
My student love this project and you'll see things you've never seen before.
