1 Tests to see how much light is reflected by one way mirrors and seeing if this can be changed.
2 Tests to see how clear you can see the other side and how clear you can make this if it's not clear enough.

Is it possible to reflect light for a hundred procent but also see through the mirror at the other side ?
