We get A LOT of questions from our listeners! So this week we decided to put the competition on hold, open up the old Tangents Mailbag, and answer a few of them! 

Get ready to learn some of our deepest secrets, like what Ceri thinks about yogurt and Stefan's milk conundrum! There are other, less dairy related things in this episode, too. Once again, thank you all for your support and for all of the amazing questions you ask us every week. We couldn't do it without you!

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
