well what i'm looking to do is make my own batman beyond batarangs, and when Terry uses them in the series they seem to retract and expand after he presses a section of the handle/base. and all i have is from small screengrabs.
from how they seem to work atleast to me would be press a section in the center and the wings pop out or pop back in. making a prop from a cartoon and the largest pictures you can find are 150x112 pixels
