    Malteser vs ballistic gel?
    how far will a Malteser travel when shot out of the cannon?
    how fast does the Malteser slow down when fired out of the cannon?
    Does the Malteser desintegrate before coming to a stop/hitting the ground?

    you should have the watermelon spinning and shoot 2 maltesers so that it punctures it in 2 places

    It looks like the malteser made the initial hole in the watermelon then the air blew it the rest of the way apart

    haha was there even any chocolate on the exit wound on the ping pong paddle? it's like it went so fast it became bloody non Newtonian.

    • a. phytophile
      a. phytophile 17 days ago

      9:27 that first one holds a bullet shape for a surprising long time. forces of radial compression must have been dead on for the inertia, like the wood splinters hold it together for just a frame or 3

    • a. phytophile
      a. phytophile 17 days ago

      on further viewing it seems to liquify and take so much wood with it that you'd never think it was a malted chocolate projectile.

  • a. phytophile

    instant malted soda. really cool to see the exploded candy uniformly dissolve in the rush of acidic sugary liquid.

  • a. phytophile
    a. phytophile 17 days ago

    3:35 nice Gallagher reference. I kinda think dry firing this air cannon might still explode a melon at that range. looked like the candy powdered on impact and before the fruit split. control test? :)

    Umm, not to be a pain, but you got it backwards, a Venturi chamber DECREASES pressure as it increases VELOCITY. Basic physics principle.

  • technicalman
    technicalman 22 days ago

    This is old, but I think the ping-pong paddle flew off the second time because the second malt ball decreases the power of the cannon fire. It's pretty typical for a faster moving projectile to tear right through something without affecting the rest of the material as much, while a slower moving projectile doesn't tear through as fast and ends up putting more force on the rest of the material

    • technicalman
      technicalman 22 days ago

      That's also probably why the watermelon explodes more with two... less power provides less tearing force and more overall impact force

    I love rewatching all their vids and in this one I just kind of picked up on something at the end at around 15:40 the wall is messy on one half and clean on the other half and of course Gav in standing in front of the clean side while dan is on the dirty, it’s very ironic considering Dan is often left dirty at the end of every episode while Gav is clean. 🙂

    3:30 Simple Newtonian physics. F=MV2.
    An object with half the mass will have twice the force at twice the speed (velocity).
    This is why it takes 4 times the distance to stop if you double the speed of your car.

    To get it faster, it would probably have been better to have used a vacuum tube to shoot projectiles out, so that the air rushing behind it does not contribute to the destruction. Like what mythbusters did for the Ping Pong, in order to get it through the ping pong bat and through flesh

  • Sparktrician
    Sparktrician 26 days ago

    The pressure in the narrowest part of the venturi will be lower not higher but the air speed will be higher. I think that's what he meant. But the air pressures and speed on both sides of a venture are almost identical, so I don't know why he included one. He could have left the venturi out and just necked it down. Am I missing something?

      I agree. They should try cutting a Malteaser sized hold in the watermelon and sit that hole facing the air canon and fire it. To see if just the rushing N2 will blow it up.
