  • machines are amazing

  • Made in Germany would have 0% failures ^^

  • @emitman85 america has easier laws for cops. as for example with the Netherlands, we arent even allowed to shoot the gun. if we do, and we kill someone with it, may it be on purpose or accidental (cause you shot the artery in his leg or whatever) you can face criminal charges. hence the whistles.

  • @lhrmeonom

    I think he meant that there was absolutely no hydraulic pressure used in that machine.

  • @IceTorch051 I think they meant the machine was pressuring on the whistle to press the brand name.

  • @gus23a No kidding!

  • god damn it! only they can make a docu on how whistles are made without playing the sound of the whistle.

  • In America we just shoot you.
