I bought this set a while back, and have always wanted to perform ring of truth. But i can't grasp how it is done.did you understand the directions he explained right away. Or did it take some time.not sure what im missing , but i just don't get the explanation. I wish he and him only explained it.cuz the other guy cutting him.off and chiming in , always annoyed me. I'm curious if you got it right away?
