Good material for weight?

Elmer's Glue?

Good idea! I may try that with some BB's. Maybe I can make it a little thinner also and it will still harden up.

Bad idea. Elmer's glue (PVA) requires evaporation to set. In an interior volume like that, it will stay liquid a long time, especially if it's thinned with water. A 2-part epoxy will work a lot better in this application.

Hmm, maybe just roll the BB's around in a pool of epoxy or some kind of glue, and just fill them into the model, they might stick enough to the wall's then and not come loose?
