It was great fun, you should give it a try, too! Thanks, Sabine, for the idea -) I found it difficult to choose a photo, because they all turned out really well. Depending on the way the M&Ms (which I'd fixated with modelling clay) are positioned in the bowl, the 'melting pattern' will change. Black glitter foamsheet provided the 'space' background. Lightsources were my three small LED spotlights, my DIY softbox, and daylight. Camera on tripod (of course), operated with the remote shutter release, fairly small aperture (I tried different settings between f6.3 and f18). I used a clear, fairly flat small glass bowl I usually keep jewellery in (anything flat and clear will do, you could also use a culture / Petri dish), and water at room temperature. And this week's theme was the perfect occasion to give it a try -) Had a bag of M&Ms at home (in fact I keep buying M&Ms ever since I first had them for MMs 'Circles' theme - that stuff is addictive!). Sabine.R told me about it on our last photowalk.
The original M&Ms melt experiment was conducted by Yan Liang & Zaoeyo of The Beauty of Science. Melts in your mouth, not in your hands? Fiddlesticks! Melts in cold water! Size of the frame: 6,5 x 5,5 cm / 2,5 x 2,1 inches
