We can make a single ray of light hit a wall and go through two or more windows at the same time, then interfere with itself. No magic, just don’t look too closely at the windows or it stops working.
We can also make two perpendicular polarizers stop blocking all light by adding more polarizers in between them. Also not magic, but the brightening is not linear, don’t ask why.
