We did one as kids about 13yrs old to prove once and for all if ghosts were real as we wanted proof if they were!

It proved without a doubt to all 5 of us that they were!
We all accused eachother of moving the glass with our fingers so removed them and the glass did move still answering our questions and then went crazy round the table until it flew off onto the foor.
You can imagine our shock!

After that I think it opened some sort of spirit door and for many years I dealt with a lot of spirit things going on!
I would not reccomend opening that door unless you know what your doing! It freaked me out!
And worse thing is you can't just talk about that kinda thing to most people as most won't believe it! Lol and I don't blame them!
But after all that I can't deny any more lol.

Don't do it is what I say!

I have so many experiences after that point in my life that would stand the hairs on the back ofyour neck and the people around me have got to whitness at times also so I know it's "real" ( that kind of thing makes you check ha ha )
