And how would you do that?
any craft store will have model glue. You can also use super glue-gel form is easier to use
Either a hobby shop or if you are near a major retailer (WalMart, Target, KMart, etc.); go into the toys section, find the models and you'll see tubes called model cement. It's a special glue.
Polystyrene cement. For some reason it seems to be less well known in the USA than Europe. Use with care; it melts the surfaces together for a tight, strong bond but stray drips can wreck a model; don't squeeze the tube!! Superglue (crazy glue) is safer to use because you can pull the bits apart again if you mess up but it not as good as cement.
