instead of trying to grab the last crumb of crisps out of the box, one could just turn the tube upside down so gravity would force the crumbs to fall anywhere you want them to land.
edit:
Maybe I don't get a certain ritual though, as I haven't eaten more than maybe 5 pieces of Pringles, I find them awfully bland and overspiced at the same time, sort of cardboard-like textured and actually not crispy at all. Call me old-fashioned but unless crisps are deep-fried slices of actual potatoes, they're what mechanically separated meat is compared to real meat.
