Randonium 

This material is believed to have mystical properties, but is unable to be studied due to its nature of suddenly disappearing.

Can occasionally turn surroundings lime green.

Person 1: Did you see what made that massive green crater in the east?

Person 2: Yeah, there was a lump of Randonium, but its gone now.
