    How about investigating whether a CD or DVD could be used as a diffraction grating for "discovering" helium in the sun's spectrum? And then demonstrating a working setup?

    Or if He is too tough, you could always identify other, more prominent spectral lines.

    Theorist already tried that one.

    If a man and a woman urinate off of a vertically large structure, preferably a tower in the city, which one's urine will hit the streets below first?

    There is a very funny (unverified) story about Niels Bohr exam as a student. So, a good project for you is the following : find a NEW way of measuring the height of a building using a barometer. NEW in the sense as not already mentioned in the story about Bohr. This should be a fun project, you could tell the story to the other students before showing your new way of doing the measurement.

    why is the barometer method accurate? I think it doesnt work in all cases if I take a tall building and make the atmospheric pressure on the top equal the atmospheric pressure on the bottom then the height would be 0
