Sounds like filter paper to me (usually a circle of the paper).
Funnel, ice cream cone, traffic cone.
A funnel resembles a frustum of a cone, which is the portion of a cone that lies between two parallel planes cutting it. The shape tapers from a wider opening at the top to a narrower opening at the bottom, much like a funnel. Additionally, it can be likened to a truncated pyramid, which also has a wider base and a narrower top.

From a distance a cone looks like an isosceles triangle.

A cone is the solid shape that matches a funnel. Both have a circular base that narrows to a single point at the top.
Tornadoes are generally funnel or cone shaped.
the answer is a cone, "elephant trunk," or cylinder shape under most circumstances.

A cone-shaped tornado is simple a tornado whose funnel is cone-shaped. Tornado funnels may also appear rope-like, column-like, or appear wispy. The shape and size of a tornado do not necessarily indicate how strong the tornado is.
A tornado is called a funnel because of its shape - it often appears as a rotating column of air that narrows towards the base, resembling a funnel or a cone. This funnel shape is created as the tornado draws in debris and moisture from the ground, giving it its characteristic appearance.
Cone
The funnel of a tornado is the result of moisture inside a tornado condensing. As the air rises it cools, allowing more moisture to condense, therefore the funnel gets wider the higher up you go.
