Show transcript0:00But will the Huacha live up to its reputation? Carrie's prepared to stake hers.0:06I think it's going to take down the army. I'm guessing at least 50% go down.0:11And that's got the infantry trembling in its boots. Grant sallies forth to light the master fuse.0:19Quick, your army is attacking. Run, Grant!0:23Then toddles back to safety.0:27It's going.0:28We got a little bit of time here.0:30They know something's bound to happen, but will these arrows all take off together?0:35Another 30 seconds, you can see multiple fuses going.0:39Or will the hwacha just blow itself to pieces?0:44Look at all the smoke.0:47The tension builds as the fuse burns down.0:51No one knows just when, or even if, the last part of this myth will catch fire.0:57Something's happening, something's happening.1:00They'll light each other.1:14It's the launch of a lifetime.1:18A spectacle not seen by man nor beast in 500 years, and every arrow but one took flight.1:29That was fantastic. I just seeing all the rockets come out of the watch at once, beautiful thing.1:36Seeing that would be terrifying, absolutely terrifying.1:43Oh, hey, look.1:45That's the one that went short.1:46It's an awesome enough sight side on. Half a dozen arrows dropped short, and the army's still upright, but this myth is far from busted.1:57Well, the army's still standing.1:59Yeah, and you know what? There's not a lot of arrows in this area.2:02Where'd they go?2:03I don't know, they're around here somewhere. They've all grouped right over here.2:08Oh wow, that's a great grouping, actually.2:10That's incredible, like they were pretty consistent.2:13Oh, they're definitely army over here. We only had 50 soldiers.2:16Imagine if we had like 3,000, 30,000, 300,000.2:22Carrie's right. The troops wouldn't be so few or so scattered, so this rocket attack would be devastating.2:31All right, so watcha, confirmed?2:34Confirmed. They all left, and they exploded.2:37Absolutely confirmed.2:38All right. That was a good one, man.2:47The watch out worked on many levels, but most of all, it was frightening.2:51All of those arrows flying into the air on fire and exploding would definitely make me turn around and run.3:01That was a success. I mean, we got all the arrows to fire off except for one, and they all went the distance, and they all exploded.3:07OK, maybe we didn't take out the army. That's just because our aim was off, but if we had been aimed right, we would have killed this army.3:14We knew it existed, but no one knew for sure what the Watcho was capable of, and now we do.
