Description
English: Photograph of "Jack" Frost (John Carver Meadows Frost) at work in his Avro Canada laboratory (photo: 1952). He demonstrates the Coandă effect. Pressurized air flows out of the end of the red tube, and then over the top of the metal disk. The Coandă effect makes the air "stick" to the disk, bending down at the edges to flow vertically. This airflow supports the disk in the air.


The image in question, was part of a film project that I was involved in as screenwriter, original author and technical consultant. In the research phase, I obtained the rights to the extant Avro Aircraft film archives and the image was a still from an original 16 mm print that was used in the forthcoming book and documentary film. At the conclusion of the project, I retained rights to the research material. Bzuk ( talk) 17:15, 22 November 2009 (UTC).
