 Item No. SCP-109 Object Class Euclid C-Addendum 109-1 Special Containment Procedures SCP-109 is currently located at Non-Critical Storage Unit 7 and requires no active monitoring. It should not be removed from the unit except to be transported to a research facility and then only by personnel with Level 3 security clearance or higher. When replacing SCP-109, personnel should ensure that it is firmly closed and that it is placed on the molded pedestal in the upright position. Description SCP-109 is a standard issue United States Army canteen, circa 1899, made of a tin alloy and fitted with a heavy cotton cover and a black leather strap. When opened, the item is seen to be nearly full of water. A seemingly unlimited amount of water can be removed from the container without changing the water level or the item's mass, which remains a constant 3.16 kg. Probes of the interior of the container report an estimated volume of 2.8 liters and a shape consistent with the outside. The water in SCP-109 is of a slight blue-gray tint, with concentrations of 20 ppm of tin and 170 ppm of other electrolytes. The water remains at a constant temperature of 19°C, but can be heated or cooled when moved to another container. Addendum 109-1 Upon the item's delivery to Site-19, it was given the Object Class of SAFE. As tests were conducted on the item, uncertainty surrounding test results prompted General ██████████████████████ to upgrade the Object Class to Euclid. Addendum 109-2 Recently, a request was filed and granted by Dr ██████ for permission to water an ochre plant growing in its office with SCP-109. Staff should be notified that Dr ██████ uses SCP-109 for this purpose for a small time every Friday. Addendum 109-3 It has come to my attention that new Class-D personnel are often dared to empty the bottle. Guards are reminded that they are to discourage such activity, and in front of the SCP-109 is bottomless. Chanting Chug repeatedly is considered unprofessional. Dr. Cline Additional Information Due to the range of tests conducted on SCP-109, this section has been provided to present test results in chronological order. Dates have been withheld for confidentiality. Test ██ Subjects imbibed water from SCP-109 report that it was very refreshing and, despite the metal content, very tasty. Urine samples from subjects were normal. Test ██ Follow-up tests to Test-1 had subjects dehydrate themselves for one full day before imbibing water from SCP-109. Test remains unfinished as subjects were unable to provide urine samples. Test ██ Subjects bathed in water from SCP-109. Subject reported increased energy and a much improved complexion following the bath. Test ██ Streptococcus bacteria cultured in water from SCP-109 thrived and multiplied quickly. Water from SCP-109 administered a subject suffering from streptococcal infection, killed nearly all bacteria, and produced a full recovery within 24 hours. Test ██ Blood substitute created using water from SCP-109, given in transfusion to pedestrian hit by a drunk driver. Subjects showed no malign symptoms from the transfusion and made a full recovery. Subjects physical therapy concluded six weeks early. Test ██ Water from SCP-109 administered a various plant organisms, all of which remained very healthy and showed no malign symptoms. One proposition for a test has been discussed for some time has been one involving a combination of SCP-109 and SCP-402. Due to the risk of losing one or both items or creating a hazardous situation, this test has never been conducted.
