Otona no Kagaku (Science for Adults) is a magazine + science project line popular in Japan. I just think it's so darn cool.

Sometimes I really wish I lived in Japan. Not because I'm dying to do one of these projects (although I think any of them would be way cool fun to do), but because American attitudes toward science, math, and technology are so dismissive and generally hateful.
I always remember how dismissive someone was in one of my college math class "discussion" sections (as opposed to the actual lecture) when I jumped up to work a problem on the board, because I was excited to do it (I also had the wrong solution!), like it was wrong to be excited about math. It was my major, asshole! (Double major, physics w/a concentration in astrophysics and mathematics. And I shouldn't have been made to feel defensive about it, dammit.)
20 years later and I'm still angered by that moment, whether it was shut-me-up b/c math isn't supposed to be cool, or shut-me-up people aren't supposed to be passionate and engaged, or shut-me-up because I am female. (Not that America has a lock on the latter, to be sure. I'd sure hate to be pigeonholed as an "office lady" in a Japanese company.)
Anyways, popular science is a wonderful thing.
