Our students came back last week from our "China Alive" field trips. The 9th and 10th grades travel in groups to various locations around China. I gave my students a 'photography scavenger hunt' to do on their journeys. Today was our critique, and one of my students came back with this shot:

I asked him how he got the shot- he has his own DSLR camera, but didn't have a Macro lens, as far as I knew.
I was right, he didn't. Instead, he took off the simple kit lens that came with the camera, and turned it around, focusing through the wrong end.
I gave it a try, and sure enough, it works! Its probably not a great habit to get into- shooting with the lens off, but if you're in a pinch and have a great opportunity for an extreme close-up, that's a valuable tip!
Thanks Shan Yuan!
