HO scale can load for a PTSX (Proleride Transportation Systems) recycled steel quad hopper. Aluminum foil tops from canned drinks, mainly Sanpellegrino,  and a few other miscellaneous foil sources sliced with scissors into 2-3" strips, rolled between the thumb and fingers, and mass trimmed to roughly 1/16-inch lengths with scissors.  A good mindless modeling activity while watching TV.   Glued with dilute white glue to a black foam core base, dulled with dustings of dark gray and red oxide chalk, affixed with Dullcote.
