A friend of mine made jynnan tonnyx jello shots: Slices of lime filled with crystal clear jello, and a sprinkling of some popping sugar and citric acid. The degree of novelty was astounding, and they were very popular.

I can see bottles being fun, too, though I expect the novelty would wear off quickly.
