I like this. Star Wars Lightsaber Ice Pop Maker. From the site:
Just add juice (or any delicious liquid) to the mold and pop the whole shebang in your freezer for 4 hours. Run a little warm water over the mold and the full saber can be removed and then inserted into the hilt.
And the best part? Each hilt lights up, so your popsicle will glow like a lightsaber.
