You know those little plastic containers of desiccant you sometimes find in the larger size bottles of pills? Well, they are not only good for 1:12 waste baskets, paint cans or canisters with the addition of a bead on top, some paint and a label, but if you open them up, they'll have either very tiny charcoal (briquets for your BBQ or coal fireplace), or beautiful crystal-clear silicone (??) marbles to use as candies in a jar, marbles for a child or to add some pizzaz in the bottom of a vase of flowers or lucky bamboo.
WARNING!! THESE ARE DESIGNED TO ABSORB MOISTURE SO IF YOU WANT TO FASTEN THEM DOWN DO NOT USE A WATER-BASED GLUE!
They're OK with SuperGlue as well as silicone, but those are the only ones I've tried. I'm not sure about using them with Magic Water or liquid resin for rising bubbles in a bottle or pond, but next time I need faux water, I'll give it a try.
