SCP-5420

Item #: SCP-5420

Object Class: Euclid

Special Containment Procedures: SCP-5420 is to be kept in an airtight 5x5x5 concrete cell with no entrances or exits. The walls of the cell are to be equipped with metal pistons on the outside that will change the size of the cell. The maximum size is 5x5x5 and can only get smaller. The Pistons should change the cell size randomly, as to keep the SCP from finding a pattern with the mechanisms. In the event of a containment breach, all vents in Site ## should be closed remotely and the on-site Vacuum is to be used on SCP-5420. The vacuum should be set to ‘suck’ and the air should be pulled in in a fashion that if SCP-5420 turns into either Gas or liquid, it could be pulled in. If SCP-5420 is solid, then it should be directly transported in a similar fashion to SCP-173 While SCP-5420 is being transported in its solid state, the vacuum should still be operating on SCP-5420. This is supposed to happen until SCP-5420 is back in its cell. The cell is to be opened by pulling one of the pistons back far enough to create a gap.

Description: SCP-5420 is a (Typically) 1.9-metre-tall substance that takes the basic appearance of a plague doctor. It almost looks like it was drawn, but tests suggest that it is made of a sentient chemical beyond current understanding. This chemical seemingly has the ability to shift its state of matter at will, changing from solid to liquid in a matter of seconds. The density of the liquid state of SCP-5420 is so little that SCP-5420 has been observed to soak into electrical wires, allowing it to escape containment easily. This is why there are no entrances into the cell of SCP-5420, As the liquid or the gas state of SCP-5420 can easily seep through cracks and escape. SCP-5420 is capable of speech and is not particularly hostile unless provoked. SCP-5420 is provoked by any people watching it without its permission. SCP-5420 has no additional anomalous properties other than its ability to change states of matter. SCP-5420 Can move by turning its bottom half into a liquid state and slithering along the ground.¹

Footnotes

1. SCP-5420 Doesn't allow us to log it's conversations, threatening breaching containment if The Foundation does. The Foundation threatened SCP-5420 with elevated security, but for safety purposes, The Foundation is not including these conversations to make sure that SCP-5420 does not escape Foundation custody.
