Filled up a plastic water bottle

I have a picture of this bottle, with all of the tiny pebbles in it. The pebbles are catching the light and the bottle appears to be filled with diamonds and other precious gems. I don’t know what happened to the bottle, though. I don’t remember ever seeing it once I returned to the States and unpacked all of my bags. I probably left the bottle behind, figuring that it was too heavy to tote back to Frankfurt. I do wish I had it, though.
