Item #: SCP-4546
Object Class: Safe
Special Containment Procedures: SCP-4546 instances are to be contained in a standard Safe-class
locker.
Provisional Area-4546 has been constructed around SCP-4546-1; access to civilians is
to be denied under the guise of a firework manufacturing facility.
Additional test launches of SCP-4546 are suspended indefinitely.
With the exception of Researcher Cardenas, no personnel within 200m of SCP-4546-1 are
to comment aloud about the anomaly.
Description: SCP-4546 is the group designation for a box of individual aerial shell fireworks.
SCP-4546 instances constantly emit a quiet crackling sound, with no discernible pattern.
Approximately 67% of people within audible range of these sounds will report hearing
indistinct laughter (described as "child-like") within the noise.
SCP-4546 instances also iridesce brightly when people approach within 3.5m of them.
SCP-4546 instances are each 0.8 m in length, and are decorated with red, white, and blue,
in the pattern of the United States flag, and bear a label reading "Forever Free".
SCP-4546 are composed entirely of nonanomalous chemicals typical of commercial fireworks.
Addendum 4546-01: On 02/01/1966, a test firing of SCP-4546 was approved in a remote location.
One instance, designated SCP-4546-1, was selected at random, loaded into a mortar, and launched.
The selected instance crackled louder and iridesced more intensely prior to being launched.
SCP-4546-1 ascended to a height of 119 meters and detonated, producing a burst of red, white,
and blue stars, with significantly less smoke than nonanomalous fireworks.
SCP-4546-1 remained stationary at its peak height.
20 seconds after the stars faded completely, SCP-4546-1 began to detonate continuously,
forming changing shapes and patterns of stars in all colors.
As of this writing, SCP-4546-1 has not ceased.
SCP-4546-1's bursts and colors possess few consistent patterns.
SCP-4546-1 produces larger and brighter detonations on certain holidays; namely, July 4, Memorial
Day, and Veteran's Day.
On 07/04/1976 (the bicentennial of the United States of America), SCP-4546-1 produced bursts
nearly five times their usual size, and created shapes strongly resembling a smiling face.
Addendum 4546-02: On 01/22/2017, Researcher Cardenas was assigned to collect routine spectrographic
data directly from SCP-4546-1.
During the task, Researcher Cardenas audibly commented positively about the beauty of the
display, causing SCP-4546-1's burst to change colors to red and display heart shapes in
addition to the usual rings and spheres.
These altered bursts reappear only when Researcher Cardenas is in SCP-4546-1's vicinity.
