I was under the impression chemists/lab techs regularly store nasty chemicals in “glass beads.” They put the nasty stuff into test tube, then melt the tube shut. The result is a glass bubble filled with poison. This makes it easier to store, move etc. The movie portrayed glass bubbles of nerve gas as a way to deploy nerve gas, which makes no sense. It also portrays glass a fragile, which isn’t true. But scientists in a laboratory storing toxic chemicals in “glass beads” is very much something that “checks out.”
