Hi Lin! For characters that decide to create something in the tubes, they may find that certain things don't stick or appearances change without warning. For example, if you try to make a character with a good sense of humor, they may be prone to an overabundance of puns or mean-spirited jokes. A creation that's meant to have blue eyes may end up with one blue eye and one brown eye (or one eye, period.) This won't always be the case! There can be plenty of cases where the projection models created work just fine, but if you'd like for your character to create something that goes awry those are examples we'd offer. We would say that they wouldn't melt or fall apart, but they may not fully form if that's a route you'd like to take.

Models characters create may not be able to venture much further than the glass building, but characters can experiment while they have the chance.

Hope this helps!
