Absolutely love the idea

Absolutely love the idea. I wanted something I could put on a beer if I couldn't finish it (after I've had a few of course). It does the job but pops off when I put it in the fridge so maybe try storing them in your fridge as putting a room temp one on a cold drink and putting that in the fridge will cause the cap to constrict and pop off, defeating the purpose. So in other words, I'll just finish my beer.
