I would aim for RC that are not based off laws like that yet....for a lot of people pushing your hand through a wall doesnt work. I have been lucid many many times and a lot of the time it was through checking the clock which worked when a hand through the wall or through my finger did not.

In saying that my first lucid dream was using the hand through a wall tech. My advice would this; when you are doing the RC while awake, really imagine what it would look like if you were in a dream, what would happened, what would it feel like , would the wall move or would your finger just slide in, would there be ripples or would it be cold and hard and be very firm? Really try to see in your mind what it would be like and you will have yourself an RC that should work a lot better then if you "just did it" for the sake of it while awake.
