Object for dissection
As we were assigned the project of taking something apart and teaching the rest of the class something about it, it occurred to me how mysterious the workings of so many personal electronics were (to me at least- I know I am at MIT). I know from general knowledge that phones are made up of tons of little integrated circuits and other little electronic components, but I had never actually seen them. So, it was to my delight that when I opened the thing up, sure enough, out of the hollow plastic case spilled about half a handfull of gravel.
