Laub Andrew made his TikTok debut with a "geography lesson" on Feb. 22, which shows the two Diomede Islands out in the Bering Strait. Big Diomede is an 11.2-square-mile island that is a part of Russia and Little Diomede is a 2.8-square-mile island that is a part of Alaska. The Diomede Islands in the Bering Strait are separated by the International Date Line with Russia's Big Diomede Island being 21 hours ahead of Alaska's Little Diomede.
