Not exactly as intended

Zen

 My mom gets really stressed at work, so I made up a Zen roller bottle for her to carry with her. Yesterday while at work her lower back suddenly started giving her severe pain. She was in so much pain, she decided to use the Zen on her back. Within minutes her pain was relieved enough to be manageable. Not its intended use, but was happy it gave her some relief. Several co-workers have requested their own bottles of Zen.
