It’s cold! A day for カイロ (hand warmers). The first time I came to Japan was the first time I encountered these portable packets. The brand my homestay family had was ホッカイロ (Hokkairo), which totally confused me because I thought they were talking about going to Hokkaido. And then I thought that was the name of the product until I saw other brands like ホカロン (Hokaron).
Do you know the kanji? (See the bottom of this post for the answer.)
Do you know how they work?
It’s a simple chemical reaction. Basically, the packets are rusting, and the heat is just a by-product of that reaction.
Read about it in English here: “How Do Hand Warmers Work, Anyway?” (from Adventure Journal)
At the end of the article, there are several recommendations/links to purchase them. The prices in dollars on Amazon seem a little steep to me, compared to Japanese prices. Anyway, there’s also an electric hand warmer made by Eneloop, which may be better for the environment. It’s available on the Japan Trend Shop, which I’m not recommending you use to actually buy anything, but it’s a pretty funny place to browse many novelty products you’d “only find in Japan”.
The kanji for カイロ is:
Train geeks and birdwatchers will like this story. It’s about how the newer shinkansen are modeled after kingfisher birds’ beaks because the guy who helped design them was a birdwatcher and noticed that nature’s designs can be pretty perfect. He also got hints from owls and penguins. The video goes on to explain biomimicry and how we can learn a lot from biology and nature.
Watch with the CC subtitles turned on to help you improve listening skills and learn some language. Like this phrase: “to make a splash” — which can be literal (a bird makes a splash when it dives into the water) or an idiom (to become noticed/gain a lot of attention because of something you’ve done).
My students will probably not get the title reference. It’s from this scene of the classic movie “The Wizard of Oz”:
This is a very powerful PSA about online bullying. The fact that it’s filled with swearing should not, I think, stop people from sharing it, even with students.
The video made me think about an article I read earlier about Twitter (“One person’s history of Twitter, from beginning to end” from Medium).
Something to discuss (from about halfway through the article):
I found this cute picture this morning (the artist has a book coming out next year):
and it made me think about:
- how my “bingo” challenge for students really is a bingo! (not 5 but 4)
- how this would be a great way to do your diary style portfolio task
- how “instagrammable” is now a word. You may not find it in a dictionary, but peope use it.
