Item #: SCP-XXXX
Object Class: Safe Euclid
Special Containment Procedures: [SCP-XXXX is to be contained at Site-██ in a standard containment chamber. All experimentation of SCP-XXXX should be licensed by the O5 council, and there must be complete valid reason to experiment on SCP-XXXX, as the majority of all test results have currently ended with death of subjects exposed to the entity. In the event of a containment breach, SCP-XXXX should be immediately checked on by personnel of Clearance Level 3 or higher. As well as this, no personnel of Clearance Level 2 should come within 3 metres of SCP-XXXX
SCP-XXXX should not be taken out of its containment chamber under any circumstances, due to the incident of the 26/12/20██ when Dr. ███████ took an instance of SCP-XXXX which resulted in [DATA EXPUNGED] and caused the death of [DATA EXPUNGED], resulting in the classification to be changed from Safe to Euclid. ]
Description: [SCP-XXXX is a plastic, 500cm3 plastic bag of 200 party poppers. The plastic bag has the words "PARTY POPPRS" etched onto the front and the back of the bag. The bag, opened when it was recovered by Iota-10 (Damn Feds) contains 200 standard size party poppers, each with no anomalous events present from first appearance. Subjects who were told to hold SCP-4065 in their hands express a sense of euphoria and enlightenment, and that feeling only amplifies when SCP-XXXX is pulled, and the 'confetti' is released.
Once SCP-XXXX's string is completely pinned, all living organisms within a 1 metre radius of the activated SCP-XXXX report feeling intense enjoyment and enlightenment; D-9281 reported, in the second experiment run by Dr. ███████ that he felt that his "deja-vu disappear." Others subjects report feeling indescribable feelings of happiness for the first five minutes that they are subjected to SCP-XXXX.
Once a subject has been exposed to SCP-4065 for longer than 5 minutes, subjects report feeling a pain in numerous organs and muscles. Subjects have reported feeling a pain in their stomach, head and (occasionally) the anus. After 10 minutes, subjects express large amounts of internal pain, and roughly half of subjects express an intense pain to expel fluids, by either defecating or regurgitating it; any attempts to do so have so far been unsuccessful.
After 10 minutes of exposure to SCP-XXXX, subjects show signs of a brain aneurysm, however, there has currently been no way to allow subjects exposed to SCP-XXXX to lose consciousness, which is a common symptom in brain aneurysms. This is speculated to be due to the intense pain that every subject has described feeling roughly 10 minutes after exposure. As well as this, numerous Class D subjects exposed to SCP-XXXX describe seeing 'happy figures' around them, although this could be a hallucination due to some sort of shock reaction, due to the intense pain that subjects seem to feel.
After 15 minutes, any subjects exposed to SCP-4065 goes into anaphylactic shock and any screams or cries of pain are silenced. Any attempts to treat the shock seems to propel the rate in which the subject dies. Autopsy on subjects killed by SCP-4065 shows that all muscle tissue, and all organ tissue was replaced with confetti, which, when examined, has resulted in an undefinable material used to create the confetti.]
Addendum: [The first recorded case of SCP-XXXX taking a life was on the 13/06██ where a family in ███████ , England were celebrating their grandmother's birthday, where an instance of SCP-XXXX was activated in their grandmother's house. This resulted in the death of 2 children and two adults - however, the grandmother, who supposedly activated SCP-XXXX, received no ill effects associated with SCP-XXXX. The grandmother ended taking her own life due to the emotional trauma of seeing her family die around her. Luckily, Iota-10 (Damn Feds) had personnel stationed in ████, England, only ██ miles away from the location of the original incident. They were originally alerted once the autopsy was published into the local newspaper, but Iota-10 was able to brand the newspaper as a hoax. After the bodies were thoroughly examined thoroughly by Foundation medical staff, they discovered a paper note inside the chest cavities of both the children and adults. All read 'Happy bday Nanna! xxx' There was no reason suggesting that these could've been ingested before SCP-XXXX was introduced.
There is not enough valid evidence to suggest that this was not just the grandmother remembering, due to the fact that she was under copious stress and bereavement when under questioning by the foundation.
Additional Notes: "This fucking thing should be locked in a massive safe, and there's no point experimenting with these things; we know it's gonna kill 'em, like, look at what happened to Dr. ███████; he almost fucked over the entire foundation. We should just terminate this thing when we have the chance."
