Seems like it would be cool for indoor point shooting practice.
Another cute thing it would be good for is irritating the old lady.

If she thinks boy's w/h cap guns are annoying, wait till she gets a load of this. Bwahahaha!!!
You guys might have it different, but my old lady needs to be annoyed by me at least once a day. If not she will find something stupid to be irritated with, on her own.
