They lived on in an old farm house and we used the Oujia board many times, our house their house wherever and contacted three main "spirits". The first being Harry Houdini, the second being an angel named Amber, and the third I cannot recall.
Anyway, after numerous times of us asking them to show themselves or prove to us that they were real, we were alone in the farmhouse one night and basically we asked the same questions, yet after the normal questions of asking them to appear to us or prove themselves to us my brother asked the board or the spirit, my memory doesn't recall at this moment, to make the indicator stick to the board.
My brother and oldest cousin tried to pry the indicator from the board and they couldn't, to this point I was almost laughing because I believed that they were just messing around with us, until I tried to pick it up, and couldn't. I could move it on the board, but could not budge it off.
We burned the board after this incident and I haven't touched or seen one since, but am almost tempted to use one again. I guess I will go back and read some of the other stories and see if anyone else out there has experienced the same thing.
