Sweets refracted in water droplets

This is another idea I got from my macro magazine. I like doing things like this - it reminds me of science experiments at school!

On my first attempt, the water droplets were bigger and you could only see one or two sweets in each one. Making them smaller increased the number of sweets refracted. Once I had the water droplets right and sharply in focus, I took several pictures with different apertures to get the different depth of field effects. This is the image with the greatest depth of field (so you can see the sweets themselves as well as the water droplets).

Camera/lens settings: ISO 200, f/40, 1/200s, 90mm, in-camera flash, tripod.
