This 'Back of spoon pulled into stream of water' is a very poor

effect (IMHO).

To test one can "weigh" the spoon above a container of water then raise the spoon after contacting the water, raised enuff so the bottom of the spoon is level w/ the water distant from the contact area, so no water displaced.
