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. And those are nothing compared to space, which some (Sam) would argue is the biggest hole of all!Follow us on Twitter @SciShowTangents, where we’ll tweet out topics for upcoming episodes and you can ask the science couch questions! While you're at it, check out the Tangents crew on Twitter: Stefan: @itsmestefanchin Ceri: @ceriley Sam: @slamschultz Hank: @hankgreenIf you want to learn more about any of our main topics, check out these links![Truth or Fail]Termite mounds: https://www.cell.com/current-biology/fulltext/S0960-9822(18)31287-9?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0960982218312879%3Fshowall%3DtrueBand of holes: https://www.sciencealert.com/is-this-mile-long-strip-of-holes-an-ancient-inca-tax-systemMolecular drills: https://pubs.acs.org/doi/10.1021/acsami.9b22595#Roman skin cream: http://cenblog.org/artful-science/2013/01/14/ancient-roman-cosmetics-skin-cream-from-the-2nd-century-a-d/[Fact Off]Ant colony fallen through holePictures in this paper: https://jhr.pensoft.net/articles.php?id=9096&display_type=element&element_type=4&element_id=43&element_name=https://link.springer.com/article/10.1007/s000400050022https://arstechnica.com/science/2016/09/bizarre-ant-colony-discovered-in-an-abandoned-polish-nuclear-weapons-bunker/https://www.popsci.com/story/science/ant-colony-escape/https://jhr.pensoft.net/article/38972/Star-nosed mole nose holesThe video!https://www.youtube.com/watch?v=UMz0Q7VbT9whttps://news.vanderbilt.edu/2006/12/20/scientist-discovers-some-mammals-can-smell-objects-under-water-58788/https://www.nytimes.com/2006/12/26/science/26bubble.htmlhttps://www.newscientist.com/article/dn10834-star-nosed-mole-can-sniff-underwater-videos-reveal/https://www.sciencedaily.com/releases/2017/11/171120090051.htmhttps://www.sciencedaily.com/releases/2017/04/170424084028.htm[Ask the Science Couch]Sinkholes / blue holeshttps://www.whoi.edu/oceanus/feature/blue-holes-and-hurricanes/http://geology.wlu.edu/intro3d/sinkhole/sinkhole.htmlhttps://www.usgs.gov/special-topic/water-science-school/science/sinkholes?qt-science_center_objects=0#qt-science_center_objectshttps://www.smithsonianmag.com/smart-news/explore-worlds-deepest-blue-holes-180959977/Flooded pit caveshttps://www.theguardian.com/world/2016/sep/30/worlds-deepest-underwater-cave-found-czech-republic-hranice-abysshttps://www.nationalgeographic.com/adventure/destinations/europe/czech-republic/deepest-underwater-cave-discovered/Mariana trenchhttps://www.nationalgeographic.org/activity/mariana-trench-deepest-place-earth/Kola Superdeep Boreholehttps://www.smithsonianmag.com/smithsonian-institution/ask-smithsonian-whats-deepest-hole-ever-dug-180954349/[Butt One More Thing]Scorpion anushttps://www.sciencemag.org/news/2015/01/when-attacked-some-scorpions-discard-their-stinger-and-their-anus Hosted by Simplecast, an AdsWizz company.

Ducks! Basically a joke of an animal, if we're being perfectly honest. They make silly noises, they waddle around, they are extremely cute and goofy looking, and they love to swim around in big piles of money! And look, you might see the title and think 'a duck isn't science.' Well i've learned a thing or two from those eggheads on the science couch and I can definitely say that you are wrong! It turns out, everything is science! Seems like a cop out, but it's true.Anyway, we sincerely hope everyone out there is doing well and staying safe!
