For details on wtf this is: https://amass.jp/15787/ tl;dr: This is a special of the famed Japanese children's show "Pythagoras Switch". In fact, it is the first part of a 2 day special episode run from early 2013 in which the concepts covered are more aimed towards older audiences; hence the title『大人のピタゴラスイッチ』. This first special is deemed 「ちょいむず」or "Slightly Challenging/Difficult", geared toward middle-school aged kids. I somehow had a cap of this sitting around on a hard drive, so I thought, why not encode it lol. I have the day 2 special, but unfortunately not the cap, just a crappy webrip pieced together from some chinese site, I'll post that too for posterity's sake, but it will be a huge step down in quality.
