Tory was buried in sand to test this myth. He was buried in dry sand up to his neck to see if the weight of sand would cause him to pass out, and if not, whether he could escape on his own. Within five minutes, Tory was able to free one of his arms. From there, it took him eighty six minutes to dig himself out of the sand. However, the Build Team decided to use more accurate conditions: they buried Grant in wet sand, continually adding water to simulate the rising tide. While Grant tried to escape, the water kept pushing the sand back into the cavities he was digging out, immobilizing him. Grant was eventually forced to rely on outside help to escape, confirming the myth that the sand necktie is lethal.
