Earlier you told me "hold a pencil up. A real pencil. I bet you can make perpendiculars in many directions, because the pencil is in a three dimensional space". Could you explain to me what do you mean by this? I try holding up a pencil and doesn't see anything.Thanks

No matter which way you old it, it is perpendicular to some plane.

Hold a book at different angles. Can you hold the pencil in such a way that it's perpendicular to the book, no matter which way you old it?
