Two small points:
1. I didn't suggest what it was, I showed what it was. I didn't know what every component in the photo was, but the common elements in the photos are obvious.
2. Lindy, to her credit, was perfectly willing to accept this mundane information as the answer. She simply wondered what was in the cannisters (so did I), and then when she found out on her own, came back and added some useful information to the thread.
I don't think she deserves to be leaned on in this particular thread. Even a little.
