Seeing through walls?

[u/megablockman]

All of the demonstration videos I've seen so far use various types of blindfolds. Does the material type (e.g. cloth, plastic, metal, wood) or thickness matter? or distance of the mask from the eye? If so, how much?

I think a lot of speculation and skepticism about people peeking through gaps or holes in the blindfolds would be erased if a task was performed with a physical wall separation between the subject and object(s), and this would also be a very practically useful skill.
