Calling all Nail Gun Experts

To all our nail gun experts, see if you can spot the trick. It is great fun though.

I'm a bit slow at this time of morning, couldn't spot it. Great clip though, those two are fantastic.

I know nothing about nail guns but doesn't the tip need to be depressed to get a nail out. Just putting your hand in front and not pressing the tip shouldn't eject one? should it?

Gun pressed down fires nail
not pressed on hand

Edit : Beaten by that much........

Looks like it has been rigged to work in reverse. When tip is depressed, it doesn't fire and vice versa.

1) Compressor doesn't appear to cycle on at all while shooting all those nails.
2) No blast of expelled air from any shot (I'd expect at least some dust to be kicked around, or some similar sign).
3) Nails hitting the metal bar...there seems to be less kickback than I'd expect from that, and less bent/jammed nails.
4) Magazine totally obscured.
5) No ejection of the plastic collation strip (usually they tend to form a big strip you have to rip off)

So I'd say that the mechanism is actually in the target bar....

Or (on second viewing) the safety mechanism has been re-worked to operate not on the nosepiece, but on a part of the magazine; it is pushed onto the black bar that is used to increase visibility of the nails.

Still not sure why it dry-fires though - I thought most nailguns had something to prevent this.

Notice the finger action when "firing" into his hand, and then the lack of finger action when shooting a nail. :D
