There's a tear, and I've put tape on it. Let's try making a Pythagoras Switch yourself! The goal of the "Pythagoras Switch" that appears on the show is here in 1/1 scale! When the ball reaches the goal, the logo flag stands up, and the familiar goal sound plays. The back is transparent, so you can see how the lock releases and the flag stands up. Professor Masahiko Sato, who is involved in the program's supervision, completely oversees it!
