Not to brag or anything.. or actually it is..
When I met a childhood friend again some years ago, he reminded me of a fantastic shot I made at the age of six/seven. With a quite simular type of pistol, I somehow managed to shoot a pea up his nose. Perhaps with a nice bounce from the upper lip. According to him, he was afraid that it would stay there forever, but eventually it got out the same way.
Moral of the story; make sure to use potatos or large peas
