I'm going to demonstrate the hand-crank air-raid siren it comes shipped like this folded up you can extend the two handles here that come together to be gripped also the handle over here clicks into place for your crank it also has a trigger on this side that you can pull to get a normal sound you pull it to get a loader sound both sounds are loud one is just louder than the other and the faster you crank the higher the pitch goes and the louder the item gets I'm going to demonstrate it first without the trigger pulled [Music] you could use this for like I said an air-raid siren even an old-time kind of a police siren or basically any kind of emergency thing you're looking for now I'm going to demonstrate with the trigger pulled and it's a louder Center [Music] next I'll show you the differences you can get between starting off with it pulled and letting it go and sliding them back and
