What makes it tamper evident
Discussion
It's a brilliant design!
When you tighten down the lid, a transparent, flexible membrane locks a huge number of colored beads into place. You take a photo of that configuration, and there's no way that the beads can be restored to their previous position once the lid is unscrewed...🚀💥💖😁
Is there an app? Otherwise how would you tell north south on the picture?
I imagine it would be fairly easy to rotate the image into alignment...
I'm also pretty sure that, once release and recaptured, the bead arrangement would be so radically randomly different, the change would be more than obvious.
