Possibly. Most of what I do centers on Newton's Laws and "Fun with liquid nitrogen" so I'm not sure what other fun things might be available.
Patrick, The following may be of interest from the UCLA Physics Department Demonstration Manual helpful: H Spectrum projection (simple large 2ft diffraction grating behind arc tubes) http://www.physics.ucla.edu/demoweb/demomanual/astronomy/light_spectra_atoms... Projection of Spectra (complicated setup) http://www.physics.ucla.edu/demoweb/demomanual/optics/spectra/projected_merc... Sodium Absorption http://www.physics.ucla.edu/demoweb/demomanual/astronomy/light_spectra_atoms... UCLA Physics Demo Manual, generally http://www.physics.ucla.edu/demoweb/demomanual/index.html Maybe if you could fit in this demo. -:) http://www.physics.ucla.edu/demoweb/demomanual/unusual/large_arc.html - Kurt
