I got my daughter a marshmallow blow gun when she came for her weekend with me. She's six, and she loved that thing! Spent the weekend target shooting, chasing the dog around, chasing me around, and generally causing mayhem and also burning off energy, so when bedtime came around she was fast asleep.
My ex wife was *not* happy when I sent her home with that thing. Seems their dog does not have a sense of humor. Oh well, not my problem.
