it's cute. but unless your breaking into a castle, it's pretty useless at point blank. |

How about a brick wall with actual mortar in it. Or perhaps actual cinder blocks that are not just loosely stacked.
I'm sure it would work on a solid wall, but I'd like to see just for seeing it sake. |

"And in much of the USA with their trailer parks and an odd fascination with wood built housing."
And in much of Europe with their lorries and castles. It seems most effective against such materials.

"Not necessarily a good thing. There is a proper speed at which the projectile will do the most structural damage to a wall. I imagine a graph of this speed would look like a bell curve and also depends on the mass of the projectile and the surface area which contacts the wall. Basically i'm saying that if it is too fast, then you get a bottle-shaped hole in the wall, not ideal for entering."
Since the projectile is launched by compressed air, it would be easy to lower the pressure and adjust the impact velocity. However, stationary mounting (such as the demonstration of it mounted in the truck bed) would allow more force to be imparted to the projectile at its maximum psi, possibly allowing a better breach of objects like the van. |

"He probably means that the rolling back wastes some of the expanding air energy. If the cannon were to be fixed, such energy would be spent on further acceleration of the bottle.
More acceleration equals more force on impact."

Really Sarah, you think that compares to a sledgehammer? |

The walls ARE kinda thin. Would like to see cement filled cinder block with a red brick facade, AND be typically re-enforced with re-bar. That would impress me. In any case, you could probably use this device effectively in the middle east with their mud huts, and in parts of south america. |

without cement it's just a single stack of bricks. You could push it over with your hand. |

Eh, big deal. A sledgehammer does the same amount of damage and is a lot simpler. |

Yea Smoothjc1, none of those walls were properly constructed with re-bar and solid poured corners. Still cool though, and I'm still bored. |

Well, I found what I'm building next summer. Now, to see whether or not I can convince a friend to let me shoot them with it... |

If you aren't going to mortar the bricks together, you might as well shoot it at a Jenga tower. |

Non-Lethal you say? Cool!
You could use this on fellow shoppers at WalMart! |

@patchouly are you suggesting that they should use that wasted energy into reloading another water jug? I can't think of any other possible use for that energy. Recoil will always be a part of that design. |
