 Item Number- 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. Several 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 discernable 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 0.8m 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 non-anomalous chemicals typical of commercial fireworks. Addendum 4546-1 On February 1, 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 119m and detonated, producing a burst of red, white, and blue stars, with significantly less smoke than non-anomalous fireworks. SCP-4546-1 remained stationary at its peak height. Twenty 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 Veterans Day. On July 4, 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 4546-2 On January 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 bursts 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.
