English experiment with "The Power of the Mind"

I've tried to find it online, and also on this site, but couldn't find anything about it.

Some scientists did an experiment with a ball dropped down a wall with pegs and a glasspanel.

The obejct of the experiment was to see if the participants could 'force' the ball to either side. There was also control groups.

The result was that those who wanted the ball to go down a certain side, had statistical more balls in their preferred side, than the control group which had it evenly spaced out.

Has anyone heard of this experiment?

I remember I saw it on TV, but not which channel or the program it was shown in.

there was something like that on most haunted live set up by Ciaran O'Keefe.
I cant remember too many details, but I know one of the experiments showed curious results. I trust O'Keefe, but not the rest of them on there, so make of that what you will!
