It's actually the bottom of a wine glass sans the stem filled with red wine. Using the original LensBaby with macro filters to get up close. To get that smooth finish, the photographer indulged in several glasses of wine. One of the hazards of photography.
This was a fun one to shoot using the LensBaby 3G. To get the multicolored blokeh, I placed the two 37mm filters on the open side of the CD under a flourescent lamp. I must have taken about a hundred shots to finally get this one right.
