Researchers can't replicate poorly described experiments, so Moshe Pritsker went to the videotape, starting the "Journal of Visualized Experiments."

Moshe Pritsker was about 30,000 feet above the Atlantic Ocean, with North America ahead of his airplane and Europe receding, when he began seriously wondering why he was there.
