Have you asked five adults this riddle? I suspect at least two of them would get it wrong or have some uncertainty about whether or not the peanut was visible.

This. Was also thinking "yes" first because of the glass of water, transparency, etc, but then got unsure: The objects might be spaced so widely that the milk or coke bottle would obscure the view due to perspective - or the peanut would simply end up outside the viewer's field of vision.

Shows that even if you have a world model, it might not be the right one.
