I take that you have found your way into the lab, already. You want to build authentic 4D glasses? Why not!
To build the 4D glasses you need:
Maybe some chewing gum. You find some chewing gum from the lecture hall. Under the chair.
Yeah, that would've been unrealistic. Who else would enjoy the gum?
Nicotine gum that is.
Put the gum into the ashtray. It becomes nicotine chewing gum. Give it to Dean.
Yes, take the glue and glue the glasses together.
