Item #: SCP-XXX
Object Class: Safe/Euclid/Keter (indicate which class)
Special Containment Procedures: SCP-XXX should be kept in a small lockbox in containment site █████-████
Description: SCP-XXX is a black polypropylene drinking straw, of regular length and 5mm in diameter, similar to those used by ████████. It was first discovered in a coffee shop by Dr. Greek, after witnessing it's effects on another customer, and after an interview, followed by type-C amnesiacs, contacted the foundation.
SCP-XXX's property manifests when a human uses it to drink a normally consumable fluid. Tests indicate that it works by connecting to the brain via electrical interaction with the nerves that touch it, in most cases the lips. It appears to be able to read a person's mind, including their past memories and preferences regarding drinks, then changes his or her drink from the original fluid to nearly any other fluid, presumably based on their past acts and recent interactions with SCP-XXX.
