    Used cars for sale - slightly acidified/melted/crushed but with GREAT history.
  • @Koopaperson
    William is 100% the type of person to enter a video unannounced and I legitimately couldn’t tell if he actually did until everyone else showed up
  • Now this is peak big kid content. Makes me feel like I'm back on the playground. Thanks for this, Mark.
  • I've never actually seen acid at word before!

    And I'm amazed nobody got hurt. None of that looked safe.

    Great video 👍
  • @user-nc2jq6eq8g
    he literally just invited all the safety third members together to destroy stuff. how fitting.
  • @kingofplayer2
    Honestly some of the best content on the platform when engineer YouTubers get together to do whatever shenanigans they feel like.
  • I still can’t believe you can do all that to a diamond! I never would have guessed how tough they are..I’m still too scared to try it myself though 😅
  • @MikeySkywalker
    Two videos in a few days. What a treat! Thank you to Mark and to the whole entire team. I'm sure there are a lot of people who help make these happen. Happy Thanksgiving!

    11:25 I don’t get why Nile didn’t choose the wood bat since wood has a buncha carbon acid would’ve eaten through it pretty easily (compared to metal at least)
  • @justin9202
    So fun fact about the anvil mark was using. Thats a common one sold by harbor freight, they do not harden their anvil's work surface like most normal anvils would have. Therefore the diamond was actually harder than the soft steel. While diamond is harder than regular soft steel it would be much more of a challenge if they tried denting a hardened steel anvil
  • “We can’t see if it’s working!”

    the iPad literally covered in lava
  • @Seed
    1:48 Mark’s hand wash detector is coming in handy!
  • @Santiago_MX
    this episode is really starting to feel like a TV show - especially the car segment. I like it.
  • 90% of my mind: "This is SO COOL!"
    10% of my mind: "Those acids and smoke fumes aren't going to leave the atmosphere or ground water anytime soon..."

    Mark Rober went full Whistlin Diesel.
  • @ronnymcdonny2
    Bro every time i hear or read the word "lava" i have flashbacks of disney's short love music video lava
  • This is the kind of thing we dream about when we were kids, and Mark Rober is doing it IRL!
  • For someone without a car and would really appreciate having those cars to commute. The car aspect touched me differently 😢😢😢
