I finally got a hold of the Airzooka by driving to the parcel depot in Aldergrove and picking it up myself.
It's a great wee yolk, a lot bigger than I expected, about the size of a bucket, it makes a huge noise when it is activated, which makes it difficult to hit people on the sly.
It does fire the vortez of air a huge distance, and there is a soild whack when you get hit. It travels at a surprisingly high velocity. From twenty feet away you can smack a set of blinds as if a ball has hit it.
If you aim it at wasps and flys they get caught in the vortex and rotate for a while before flying off (unharmed). It also causes psychological damage to cats, but that's another story.
