How Not to Use a 7-Eleven Microwave

Pity the fool who had to clean up this mess: A microwave blew up inside a 7-Eleven in Beaverton, Ore., on Tuesday, spewing not the remains of pizza or nachos but … urine. Officials believe someone was headed to a drug test with a clean sample of urine bundled up in a hand warmer when "they decided to microwave it at 7-Eleven," a police rep tells KATU. Unfortunately, the individual forgot to remove the hand warmer from the sample. As Gizmodo explains, a hand warmer contains iron powder, which is no bueno for a microwave. Police hope to use security tapes to track down the culprit, who fled the scene. (More weird crimes stories.)
