Why is Japanese lemon tea bitter? 19th/Sunday/Sunday tea time to solve mysteries~~~~~~~~~~~~~~~~ NHK Einstein's Eye, which was broadcast the other day (4th), was very well received thanks to the many people who watched it. Thank you. A staff member brought me this explanatory panel today. This was not shown on the broadcast, but in fact, there was a special camera that followed the mystery of "the astringency of lemon tea", but it was cut due to time constraints. And this is the panel that I was planning to use for the explanation on the day, which was shelved. . . I recorded it, but it's a shame! So, I will do this commentary again on Sunday the 19th (Sunday Tea Time)! (I don't have a TV camera, but...) I would like to make effective use of the panels I've been given.
