Would take a little bit of doing, but rig the box flaps to a platform inside the box, then pour all the glitter on that, so that opening the box raises the platform and dumps all the glitter.
Rather than a platform, I’ve been wondering if you could rig it so opening the box opens some holes on the bottom, so they think they dodged the worst of it, pick it up to dispose of it and get a desk full from underneath.
