Escape The Lab

Permanently Closed - It's the last day of the summer term. You are strolling happily through the narrow school hallways when you hear someone call out in the distance. The sound is coming from the science lab. You and your friends enter the lab only to hear the door lock automatically behind you. Through the window, you can see your classmates getting on the bus and your teachers driving away in their cars to enjoy the long break. Your calls for help go unheard. You are the only ones left behind. You notice some papers on the desk with strange symbols on as well as lots of locked items. Your only way out is to crack the codes before the caretaker locks up the school for the summer.
