We... have tried something similar to what you're describing, but have yet to make it work. The incense, however it's collected, always manages to dissipate no matter how tight the container or what form it is in. We are always left with nothing, or an unaffected sample.

It would be a fair statement that we haven't tried everything and I certainly haven't ruled out it still being possible, especially with so many promising new minds to study it. What was the idea you had?
