Podcast:SciShow Tangents Published On: Tue Apr 28 2020 Description: Humans have been digging deep holes for fun and profit since time began, and some animals have been doing it for way longer than that! And all of those holes can't hold a candle to some of the natural holes the Earth's got going on.
