I used to shoot eggs in my back yard and made a wish with my mates that we would buy some manequins...to increase the fun aspect - we were shooting chick peas through a hoony gun (PVC pipe with rubber glove finger over one end) - This sounds like a step above! Wont be long before these targets actually walk and run and fire blanks back...what a great idea, glad its Australian, glad the idea worked so well.
