okay we have a sealed room (lets just say its stone made out of stone blocks) 2 meters by 2 meters by 3 meters.
the vents in the room are 3 inches wide with metal grates over them (so no coming in/out via the vents).
There is One Door in or out of the room (and its a security door) with an armed marine in front (and a couple cameras).
in the middle of the room is a small pedestal type table (no way of hiding anything under it) with a small velvet pillow holding a glass of ice.
The door is then sealed with forensic tape and then locked. (the marine is told to shoot anyone trying to get in the room)
3 hours later the room is opened and the glass of ice is GONE the pillow is wet and there is a handful of diamonds on the pillow.
Your challenge is to tell
1 where did the glass go??
2 where did the diamonds come from??
