1. there is a *treadmill*.
2. on the first day they give you a *tray* of food and it has a *spoon*.
3. there are vents and various thing along the wall that look like they are screwed together.
4. there are fluorescent lights which means there is either a high voltage or high current power supply hidden within the wall.
