"Twist". The liquid is water but because of the high shutter speed, water "freezes" and thus looks like a gel. :-) I was surprised by how lifelike and entity-ish these droplets became once captured microscopically. I take these in the white enamel sink in my small NYC pre-war building apartment. Shot with a CHDK-hacked Canon Elph. The camera I hacked could not shoot high-speed until it was hacked with a set of Canon-proprietary firmware scripts. 8" x 10" printed on heavy archival paper. Watermark does not appear on print. The image uploaded on Etsy is a low-resolution image. Detail in original is much sharper.
