Recently dismantled a TV and its backlighting consisted of thin cfl tubes. This gave me the material to try something I've been curious about for a while!
I sealed some yeast in a little section of tubing for a friend's birthday (his last name is Baker). Kind of a shitty gift as i doubt it would survive as a keychain but I had fun making it (and its failed predecessors).
Here are the other attempts, from left to right: pepper, red and blue food coloring, yeast 
I made this yeast keychain

I'm going to pretend it's an emergency vial of ricin, for your enemies

And here I was running out of ideas of what to encapsulate!
BTW if someone has an idea of something cool to do with this, I'm all ears.
I bought phosphorescent pigment with the plan to make little canisters of ooze from TMNT 2 but not sure what to mix the pigment with...ideally something non flammable, I've tried water but it wasn't super conclusive.

The liquid ones are giving me tiny lava lamp vibes. I would love to see then lit by an led or something. But I think they would look awesome as necklaces as well.

Some magnetic dust would be cool to see how magnetic fields are around us or something or iron dust

Oh yeah good idea! I'll keep it in mind for next time I play around with that
