The answer? Because after about 15 minutes they're not nearly as good. That minor hiccup aside, the YouTubers at Astonishing Studios have created this to celebrate the glorious food-like item that is the chicken nugget.

It only holds a couple of cartons, but without any way to heat -- of course Japan has that figured out -- or cool them, that sounds about right.
