Hey guys,
I've got a book of magic tricks and there's one trick involving two tubes that are seemingly empty, and from which the magician produces a number of items.
I've searched the internet, and found a video of one version of the trick being performed (see http://www.youtube.com/watch?v=981cJIps0E0), but nothing else.
Can anyone help me, as I would like to know if there is a quality version of this trick available to buy...
Many thanks,
James
