Item #: SCP-4595
Object Class: Safe
Special Containment Procedures: SCP-4595 is to be contained in a 1mx1mx1m concrete cube within a 5mx5m standard containment chamber with the entrance puddle on the top face. The walls, floor, cieling, and door of SCP-4595's containment chamber are to be lined with 1.4 cm of stabilized lithium-7.
Description: SCP-4595 is an opaque liquid substance that takes up a negative volume. When poured onto any surface, instead of acting like a normal fluid and filling a space, it creates new space inside of whatever surface it was poured onto at a ratio of 1:100. On a 1cm thick plate, pouring SCP-4595 will result in a 1m deep hole all the way through the plate, where when viewed from the side it shows to still be 1 cm thick. The only currently known element that SCP-4595 has no effect on is lithium. SCP-4595 has a color similar to SCP-4595 is very viscous, and impossible under any means to swim through, and any attempts will result in the subject sinking into SCP-4595 and [DATA EXPUNGED].

Addendum-4595-02:
D-1714 was ordered to touch the surface of SCP-4595, the subject submerged his hand into the liquid, and it immediately bound to his skin, creating anomalous geometry within his flesh. D-1714 pulled his hand back in surprise, subject was removed to have his hand scraped with a dull lithium blade to remove SCP-4595. Liquid returned to containment chamber with lithium bucket.
