Guess what? You can. What I thought was going to be a disastrous kitchen experiment, turned into a really fun project. So much, that I was sad when I ran out of balloons, because I wanted to make more. The only part of the experiment that didn't go too well, was when I first attempted to make these using a water balloon. I thought it would make sense to use a water balloon because it's smaller than regular balloons. Oh my. Big mistake. Yes, it's smaller, but the latex is also very THIN. Therefore, when you pour hot melted chocolate on it..... KAPOW! It explodes. Chocolate. Went. Everywhere.
I might still be cleaning blue candy melt off my kitchen ceiling 10 years from now.
But, consider it a lesson learned. And a good laugh. Use regular-sized balloons, just inflate them a tiny, tiny bit.
