Wise men have long pondered how magnets work. We all know the answer is “magic,” but Ceri and Hank have to keep up the illusion that science is real, so please humor them.

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: @hankgreen
