If I'm looking for something and can't find it despite all signs pointing to it being nearby, I'll try to continue looking while upside down. It's often helpful for I think the same reasons that you describe. One time, I was looking for a set of keys which had been tossed over the aisle partition in a grocery story and promptly disappeared. We tore that place apart and still couldn't find them. So I was laying on my back on the aisle floor so I could see the search area with my head upside down, and there they were. They had bounced and were hanging from the bottom of one of the shelves. When in doubt, do something weird.
