I'm currently a junior in high school, and I'm really interested in physics, especially particle physics and quantum mechanics. At my school, everybody needs to do a big senior project to graduate, involving multiple papers and about 30 hours of work, usually to build something or organize a community event. Most people end up restoring an old car or something similar, but I would really like to tie in my interest in theoretical physics. I still have another 6 months before I need to know exactly what I'm going to do. Does anyone have any recommendations for a long term project involving these areas of physics? My first thought was to build a small particle accelerator, but I don't have any experience working with electricity, so I'd probably accidentally fry myself from the high voltage. Other ideas?
