Is that what they call it these days? Back in my day (wait a minute I'm 18 :-P) they were f**k bracelets. But anyways, they are LDPE so I'd imagine that they burst about 15-40 psi. But I think you would have issues with reliability and supply (unless you are a chronic soda drinker)

Yes, this kiss my bracelet concept is new to me as well. I would think one of those things would hold a pretty good amount of pressure. They're pretty sturdy.
