I wanted an unusual shot to show off the results from my recent soda can label embossing project, and had some success using this unusual method.

Clockwise from upper left: Glass in air, glass in oil, color-corrected image, final image with background touch-ups and lens correction.

There is a classic physics demonstration, sometimes disguised as a bit of stage magic, in which pieces of glass are made to disappear by immersion in a liquid that has the same refractive index as the glass itself.

I had a Pyrex glass beaker of about the diameter of the spiral I wanted, and I decided to experiment with the oil method for making the beaker invisible to get the shot. It’s a bit messy, and there are some things I’ll do differently next time, but it works. Check out the details, below.
