    8K… are you actually recording in that now or is it purely for the bitrate?

  6. Payne Fam Adventures says:

    Love the video. Live how Dan had a different sound for each explosion. Thanks for the great education.

    Even at low res for 100000fps it’s still better res that 99% of youtube videos…

  9. Brian Cothran says:

    Great video! I had no idea that the color of the liquid indicated the temp range. I’m glad Dan wore eye protection because that flying glass could have been bad!

    • Calum Sherwood says:

      +Sola i mean if you really wanna see slow mo gore there is a video of a guy being executed via point blank gun shot in super slow motion. You can see the shock wave going through his whole body. Dont think dan and gav shot that one though

    • Jordan Wagner says:

      +Calum Sherwood you do know possums aren’t people, right?

    • Coffeewind says:

      +Jordan Wagner Most of them, anyway

    • Scott McMahon says:

    I love your ‘Planet Earth’ narrator voice, Gav

  12. That Dude says:

    Glad you didn’t test with real sprinkler systems. No one ever tells you that the water is black when it first comes out…

    • Humble Soldier says:

      In the older sections… yeah… but when you have coworkers left and right accidentally smashing the sprinklers setting off the system flushing the pipes it’s not so bad.

    • Skyler Parsley says:

      That’s only in older ones where the water has been sitting for a long while

  13. Happalula says:

    i love how once again Dan takes the brunt of things and Gav is all “oh, bother me, a droplet has just hit my shoe. how outrageous!”

  14. Daniel Jensen says:

    Just casually waving about $100k plus of camera at the beginning there…

    Spot on David Attenborough impression at the end with the possum.
