craftgrrl | Clear glue sealant stuff.

OK, so maybe everyone here can help me. I was in Michael's the other day, and I saw this kit. It's basically a kit where you can put objects into bottle caps, then you pour this glue stuff on it that dries clear and you get little decorative bottlecaps. What I'm wondering is where can I get a glue or sealant like this? I want to do something similar, only not with bottlecaps, but I need to know where I can find some sort of glue that I know will dry clear, almost like a plastic or something. Anyone have any ideas? I've seen something called E6000, which says it's glue and sealant, but I want to make sure it will actually work. I would like to seal a piece of bone inside something... I'm still not sure what yet.

Anyway, enought of my pitiful rambling. It's time for bed for me!
