Little nipper warning
Long-exposure fireworks shots
While attending the International Fireworks Show in Ottawa, Canada [August 2012] photographer David Johnson had his camera in hand to document the night. When Spain’s entry into the competition began he decided to try something a little different. David tells how he accomplished the effect:
The technique I used was a simple refocus during the long exposure. Each shot was about a second long, sometimes two. I’d start out of focus, and when I heard the explosion I would quickly refocus, so the little stems on these deep sea creature lookalikes would grow into a fine point. The shapes are quite bizarre, some of them I was pleasantly surprised with.
Spot the fake smile: Take the test!

How to reduce chocolate cravings
Use of a clay modeling task to reduce chocolate craving
Jackie Andrade, Sally Pears, Jon May, David J. Kavanagh
Appetite, Vol 58:3, June 2012, 955-963.
Experiment 1 showed that spending 10 min constructing shapes from modeling clay (plasticine) reduced participants’ craving for chocolate compared with spending 10 min ‘letting your mind wander’. Increasing the load on verbal working memory using a mental arithmetic task (counting backwards by threes) did not reduce craving further. Experiment 2 compared effects on craving of a simpler verbal task (counting by ones) and clay modeling. Clay modeling reduced overall craving strength and strength of craving imagery, and reduced the frequency of thoughts about chocolate.
