Recently, I bought an old box of magic props from the late 1950s/early 1960s, and it contained some 65ish year old flash paper. People frequently ask in magic social media groups, “Does flash paper go bad?” Well, let’s find out!
I’m amazed that it worked as well as it did and that it didn’t burn my fingers!
I think the issue that people have with flash paper is that they store it wet for safety, which is absolutely what you should do. Then dry out what you need to use a few days before you need it. That said, I think the paper sitting wet in a sealed bag over time will deteriorate. That takes years, and you really should be buying decades worth of flash paper at one time. It’s something you really should be buying a few months supply at a time. I personally wouldn’t want to store a ton of it at home.
Be safe.
