Never one to hide from the truth, these bombs are not good to make in a humid environment. It was definitely way too humid when I gave these a try.
After pouring into the molds, the citric acid, which gives the bomb its fizzing power, continued to fizz right on up and over the molds. They aren't pretty to look at, but they work. I hope to give these another try when it is less humid, which will likely be around the time these are scheduled to make an appearance on the blog!
