I guess we've all seen ghost movies where objects appear to pass through spectres in an eerie fashion. Camera tricks and creative technology of course.
But when you witness a similar event in the same room, without any obvious trickery, it tends to make for a 'Say, what?' moment.

In this video, a silk hankerchief is wrapped around a walking cane and held with one corner in either hand.
Without any awkward moves, the silk simply melts through the cane in an astonishing manner.

This is repeated in slow motion to give the spectator an even chance of discovering the mystery. I'm happy that this is the closest I've come to observing an actual ghost.

Can you pick the secret? Watch here.
