They're those little balled up/tied up tea leaf/flower bundles that you pour hot water over, and they open up into beautiful bouquets. And of course tasty teas. I love them! Here's a better description
I think I'm fascinated with them the same way I used to be with "Magic Rocks." Remember "Magic Rocks" (These things here).
I was really into chemistry when I was younger - I had a pretty cool chemistry set, and I figured out how to make my own Magic Rocks by adding various metallic salts. Sometimes (against all precautions, don't do this) I would put random chemicals in there with the crystals and chlorides - once there was some sort of ferrous stuff that turned into what looked like tiny poppy flowers - I could never replicate it again. Instead of using watered down silicates like the commercial magic rocks used, I instead would use a two-part silica gel that hardened, and it would keep them forever. I wasted so many test-tubes and beakers doing that, lol.
Next house I buy, I'm going to make sure I have a laboratory! =)
Better go back to work, I am doing a ton of concept art for some upcoming projects that should be bad-ass.
