SciShow Tangents is taking a short break, but we didn't want to totally leave you hanging! You're about to listen to a rerun of the Light episode, but with a special twist: we recorded a new Ask the Science Couch and Butt Fact! 

Next week we'll be posting another of these Enhanced Classics, then we'll start releasing regular, full-length episodes again. Thanks for hanging with us!

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
