Magic Forums

I just made an account, I have been enjoying topics on this site for a few years now, but since yesterday, my sister has been using a Ouija board, she is claiming all sorts of things, from Shadows, to poltergeist, she made a Ouija board out of a sheet of paper, I am no expert on these boards, nor do I want to be, and she is also using a quarter as a planchet. When we came home from school today, she made another 6 boards, after she burned one last night, she thinks she knows what she is doing, and something I chuckled at was the fact she is using neon pink yarn as a circle, she is using one right now actually, right next to my room, where she says she is getting the best results. She also broke what I have always believe to be a big no-no, using a board with only one person, and taking your hands off the board without saying goodbye. I am still in the "broom closet". I really don't know what to do, do I kick myself out of the closet, and confront her on it? Advice would be great!
