This product is a 1/1 size commercialized goal that appears in the popular corner "Pitagora device" of the program, which carries marbles with a karakuri device. When a ball enters the main body, the flag rises and the familiar goal sound "PythagoraSwitch ~ ♪" is played.
In addition, the back side is transparent, so you can learn the mechanism and structure from when the ball rolls down into the main body until the flag pops out and the sound flows.
According to Masahiko Sato, a professor at Tokyo University of the Arts, who supervises the program, there have been many requests for the commercialization of the entire Pitagora device, but he dared to create something around him with ingenuity. I heard it wasn't there. However, even when a goal is scored with a device made at home, it is said that it was released this time because it can be enjoyed more if the familiar sound sounds.
The main body size of Pitagora Goal No. 1 is W120 x H156 x D40 mm. Uses 2 AAA alkaline batteries (sold separately). A ball and a "mini hint" that can be used as a reference for making a Pitagora device are also included.
