Back in 2013, the sand dunes of Michigan City, Indiana swallowed a six-year-old boy. It took rescuers nearly 4 hours to dig him out of 12 feet of sand. It was a phenomenon that scientists hadn't studied in-depth. But Facebook recreational naturalists were on the case.

In this episode of Endless Thread, producer Grace Tatter and host Ben Brock Johnson go down an internet rabbit hole and bring bring us an explanation of what happened, the coexistence of miracles and science and even the including the six-year-old boy who's now an adult.

"We're pro-portal and we're pro- tree hole," Ben says. "Basically anywhere there's space, we want to explore it."
