This is a novel item to add to your platform/stage show! In effect, an examined necktie is coiled up and placed on a flat tray; performer holds the tray in his hand.
Next, with musical accompaniment, also with command from the performer, the broad end of the tie slowly rises like a cobra's hood, going higher and higher, till it rises a foot high! After a while the tie slowly sinks down on the tray, which is removed, handed over to the audience for further examination, if desired.
This is almost self-working, requires just a little 'handling' practice.
