They've worked for me and my friends before and its scary! I know they weren't faking because sometimes the planchette moved really fast and said things we wouldn't ever expect. I've had lots of good times with the ouija :) Sometimes it didn't work at all for me though, so idk.
That's for you to decide based on your personal beliefs. But you should be careful as I've heard many scary, real stories from friends who have played with Ouija boards. They don't 'predict the future' they supposedly allow you to communicate with ghosts/spirits etc.
I guess it depends on what you believe. I really can't see it working for someone who didn't believe it could. Myself, I don't believe anything can predict the future, as it is unwritten and it changes daily due to the decisions we make.
I don't believe so, I believe it's all in the person's head.
I wasn't aware they were supposed to predict the future, I thought they were supposedly used to speak to the dead. An 8-Ball is used to predict the future. :-)
I'm not sure. I do believe in ghosts, and other spirits though so i guess it probably can. I'd never try it though.
Absolutly not in my opinion
