The diameter of the spout of a regular kitchen funnel is about 1 /10 that of the upper bowl. The almost cylindrical tube below the conical upper part that opens into the spout can vary in length. Funnels are made of either stainless sheet metal or plastic. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
