@rcs914: A bullet fires when a pin hits the rear and initiating a small explosion that then ignites the powder, there must be a spring to propel the pin with sufficient speed, it might be inside one of the components and not visible on the picture though.

@Inphoarius: I'm sure it's a friendship thing, but it is registered on his name and management, I'm sure korea would host in a more wired up country but they would keep their own stuff under their strict control, registered to kim il yong himself I imagine, it IS a strict society, so yeah accepted as a friend but not…

@deathgleaner: Mine says 15 mins now

@psychiccheese: There are pens converted to shoot small caliber bullets, they WILL look carefully at pens.

@rotaryfreakjoe: Until you stand behind it in a shootout :)

@oogabubchub: Maybe it would come as the metal parts with a plastic mold, pour in concrete to complete.

@YellowRex: The barriers are around israel, since they are to keep out bombers from israel, it's israel who has to put themselves into a concrete prison not the other way around, no matter how much the palestinian supporters wail about it and film that bit where it make an alcove.

@philselmer: Many people won't get that you are joking, but those people are idiots anyway so it doesn't matter.

@Marvin Barnes' Time Machine: it would make more sense to me to build a platform just out of reach and attach a small boat for repaircrews.

@FooFighting: Many countries get a large part of their electrical energy from waterfalls or dams, canada is an example of a place where they get a lot of power from falls like niagara .

@Kardster: I find it quite astonishing how long ago they already managed to lay down cables all the way between Europe and the US, I assume nowadays that's not a big issue at all, especially when it is an area without sharks (they tend to attack cables with electrical signals).

@FooFighting: When I pedal on a bike I make energy, that energy gets transfered to the rearwheel and moves me forwards, it's very handy and ingenious.

@Romi Mahay: Isn't video.google.com like 30 minutes from the outset? I guess youtube is for funny cat clips and the president saying stupid stuff and not for serious productions.

@Fase: They have special users and even sponsored users, and then there are big companies and governments, those all get special treatment, plus they put up videos themselves too.

@deathgleaner: I know they have 2 ratings for normal users: in good standing generally and in good standing in respect to copyright, I guess you need to be in the green on both counts for a while to get longer times?

About half of the youtubes I come across are longer than both 10 and 15 minutes.

@That Guy: Barrel + spring = alert, even without a bullet.

@superhappyfuntime: Nah there are delays due to security checks :)

@Kerensky97: The barrel is inside of it, looking like a barrel, and it'll need a spring too, when you see a barrel and a spring you know enough.

@Izod517: Only after an android is developed that can assemble it in seconds.
