Science Fair Physics Ideas - Win the Science Fair!

[Aspekt]

I've entered the science fair this year and my physics teacher would like the class to do a project relating to physics. I was wondering if anyone had any ideas that would completely blow away my teacher and the judges at the science fair. Something possible to do that is. Any ideas??

There's a big thread on science fair projects.

That said, you'll usually get more mileage out of a well executed 'mundane' project than a poorly executed 'spiffy' one.
