An old Thayer item c. 1942 based on the Genii Tube beautifully re-created by Mel Babcock.
Effect: A wood tube about 4 inches square and 13 inches long is shown. It is hinged on one side and is opened to show the interior empty. It is closed and a silk production is made from one end.
Like the Genii tube but made of wood. No metal and no moving parts. Use your own silks.
