Here's my latest Supergirl fan fiction story (#87), "The Return Of the Terrible Toyman". It's set during the "vacation week" between Christmas and New Year's (when half of the Supergirl Team is out of town). The Toyman, One of Clark's and Kara's long-time foes, reemerges, and must be defeated in a battle of wits and high-tech science.

And yes, there really is an explosive called flash cotton (or guncotton) that is derived from ordinary cotton. And, no, it has nothing to do with Barry Allen (as Kara initially thought!). Here's a little Christmastime "Fun With Flash Cotton": https://www.youtube.com/watch?v=YBFTBJyV9BU&feature=share
