Welsh company BCB has developed what is essentially a potato cannon on steroids. Called the Wall Breaker, this pneumatically charged cannon launches water cooler bottles at 984 feet per second.

Need to break through concrete in a hostage situation? No problem. Want to rip a giant hole through a cargo van? They have you covered.

This was developed for the British military, so I’m not sure we’ll be seeing a consumer version available anytime soon. Impressive all the same.

    Not as impressive when you realize that those are all unreinforced concrete block walls.  Let’s see what happens with a wall built to modern building codes.

      They aren’t even mortared together, they are just stacked.  I could throw a boot and it would be almost as effective.

    Cool device, but that video isn’t doing them any favors. The music is completely inappropriate and the tech specs detract from what you’re supposed to be watching.
    Also I can’t help wondering if small explosives wouldn’t be a better solution. Smaller and lighter, and you don’t need to tow around a honking great cannon.
    Still, fun at parties.

    How does this compare to a packet of C4 the size of a deck of cards?

    Interesting…but can it knock down a cinder-block wall?

    I want one of these for the office!

    Yep. That’s the only way to deal with a Transit van.

  9. I have neighbors, I want one.

    Sure beats delivering water bottles by trolley, though.
    As far as their claim it won’t hurt those inside, I’m not sure I’d like to be under the wall as it collapses, though.
