This problem is more difficult than it appears. One one side you have rotational inertia to deal with. On the other you've got fluid shear. I bet you can't get this right. If you don't, please subscribe to help fight the epidemic of everyday ignorance.

    Oh man, I thought I had you too. Alas, my evil plan has been foiled. And I would have gotten away with it if it weren't for those meddling kids.

  • @bassman615 ha YES!

  • I think ice but im on iphone so i dont know

  • 0:20 alli can say

  • Did anyone else think he was gonna show us how to make a gravity bong at the beginning?

  • I'm guessing it's liquid but idk cause I'm on iPod, can someone please tell me

  • I'm sorry, destin, but it took me a good fifteen minutes to finish the video. I was pressing 2 instead. The way you fell back after being hit was PRICELESS!

  • best reaction to getting nailed with a ball:)

  • These guys are amazing, they're like the Mythbusters of youtube. Haha.

  • I didn't click at first because I thought the test conditions were too flawed and it could go either way. So I was right. And in the second video where you said everyone was wrong, using that premise everyone could just as well be correct thus, no one would have to subscribe. I'm going to subscribe anyway because you are a cool dude and you have a sharp brain.

  • I was genuinely surprised by this experiment's result. So much so that I DID subscribe. Incidentally, very intelligent scientifically minded people who retain a high degree of religiosity intrigue me. I just found your reddit comments and am currently reading through them with considerable interest. May I ask, do you have any experience with the skeptic community (eg. the SGU, James Randi,etc)? I think it may be a gentler more rational introduction to freethought than going the r/atheism/ route.
