SCP-377
Object Class: Safe
SCP-377 is a metallic mass that can liquefy and solidify at will, regardless of the temperature of the environment. The mass appears to be tungsten, even though tungsten melts at 3,422°C. It was first identified in ████ ████ ████, USA. The Mass appears to be alive in some sort of way. In its normal state, it is a solid 6” by 6” cube, when shown to various objects and things, it does not react to any but water, when exposed to water, the cube liquefies and tries to get as far away from the water, by running to the corner of the room, and when the water was brought closer, the mass escaped to a different corner. The water when first brought into the room, it was brought in an opaque container, but the cube immediately liquefied and escaped to the corner, this means that the metallic mass does not, or doesn't have to see the water, but can merely sense it. Upon further testing, it appears that the metallic mass can sense water within a twenty foot radius around it. When the mass was put into contact with the water, it started to dissolve, but almost immediately pushed into the side of the container it was in, and tipped it over and escaped. From this we can assume that the mass lacks the ability to jump, and that water can destroy the mass, therefore the mass will do anything to get away from it. When in dire circumstances, the mass can move at up to 25 MPH. When the mass was picked up on the bare skin of a D-class personnel, nothing happened, and when forced into its liquid state and then picked up, the mass was still room temperature, and not 3,422°C.
Not much is needed to contain the mass, so far the mass has made no attempts at escape. The mass does not need food, and can seemingly survive in any temperature. One security camera is in its cell, the mass usually stays as a cube and will spend up to two and a half weeks solid, but its time as a solid state can be as short as a few minutes. When it does become a liquid, it does not go fast, at normal pace, it goes at approximately 4 MPH. When the mass is a liquid it appears to wander around randomly in its cell, when a climbing structure was introduced to its cell, the mass seemed to spend most of its liquid time around the structure, indicating it enjoyed it, then a new, more complex structure was introduced, the mass became more active because of it. Because of it apparently liking activity, twice a week it is put in a hamster ball and taken outside with supervision. The first time it was tried to be put in the hamster ball it did not know what to do, it seemingly did not respond to people talking to it, but the mass is intelligent enough to have realized the walk schedule by now.
