Summary: How to open the bottle: Just pull on the tie down ring / eyelet thing. It comes right off. I'm assuming there are more people like me out there, that picked this bottle up, and believed that the eyelet would be secured to the bottle and that twisting would open it... because that's typically what eyelets are for. As a secure mounting/hanging point on an object. And it'd typically make no sense to pull on it, because they are typically built to withstand such force.
