Hey, look a scientist from the local college was here! She left some things behind by accident after presenting to another class about the discoveries made by Marie Curie. Is it? Can it be? It is! Next to this box is a lump of Radium, the second element Curie discovered. Don’t worry too much, though. This is low-level radiation and the Radium is not pure. You’ve got plenty of time. You’ll be fine. Take a good look. Now you should stick it back in the box. The box is thick enough to protect us. What do you mean it’s locked? You need to get that lump back into the safety of that box! You have 45 minutes. Don’t ask what happens if you fail.
