Sketchy Games

Ok I hope this is in the right section for this thread.

Basically when I was in school I knew this game where I asked someone to pick a playing, any one, and I told a story....the story would finish with me saying "now imagine the card is floating on top a swimming pool face up".

I would then guess their card, does anyone remember this game as I have forgotten how to play it?

I'm asking because when I'm with friends we like to play sketchy games with each other, be it stiff as a feather or strange card tricks.

If anyone knows of any mind games or anything paranormal we can do please let me know.

Many thanks
