Yasuo Amano, a Tenyo collector, author of the Japanese blog Hey Presto, and all around creative guy recently bought a package of what is known in Japan as "Fan Shaped Sausage." It appears to be a cross between salami, baloney, or perhaps a luncheon meat as yet undefined.
He took out a few slices, put them on a plate, and saw something that no one else in Japan noticed, which is pretty impressive considering its population of almost 200 million people. Said slabs of meat can be used to do a well-known magic trick (or, more rightly, the optical illusion shown above). But it all looks so innocent on the plate.
Discovered by Joseph Jastrow in 1889, magicians have been performing this for years and calling them "Magic Boomerangs." Two pieces of identical size and shape, when placed one below the other, produce the uncanny illusion that one is larger and the other smaller. Take another look up at the lead photo: that ain't no baloney! Both pieces are exactly the same size.
The question of why it looks so amazing can be answered by the first magic set produced in Germany after World War II, in which I discovered said boomerang trick with props that were short and very squat. This produces a much stronger illusion that what magicians have been futzing around with for years.
If you want to do magic tricks with your canapés, then you may attempt to order the "Fan-Shaped Sausage" from its manufacturer.
As an added bonus, since we're still on Yamano's fascination with making magic tricks out of edibles, take a look at this video, in which he manages something miraculous with a French fry and the Tenyo trick "Zig Zag Cig" invented by Hiroshi Kondo decades ago. If you are a habitué at your local McDonald's, and buy a "Zig Zag Cig" on eBay, you'll find this to be lots of fun and fool the customers.
