Objects classified under the EA class often do not exhibit pronounced anomalous properties—and so the Snares remained in the Research Institute 7's sample storage for a long time, overlooked by scientists. However, stalkers with a keen eye immediately noticed the new curiosity and even accidentally discovered its unusual property—any object weighing exactly 3.14 grams cannot cross the artifact's permanent static field, turning into ash on contact. Scientists believe that the artifact draws energy to sustain its static field from the destruction of molecular bonds within such objects.
