 of course they pop. That's part of what I love about working with balloons is that it is constantly temporary. There's never a moment where you're like, oh my God, I'm done. This is my masterpiece. I can sit back and relax because they're constantly oxidizing. They're constantly shrinking, changing shape. If there's a change in humidity, there's a change in the balloons. And so it's like a constant work in progress, which means you can just continue tinkering.
