get one of these
a .50 cal air gun. You would have to find a retailer in Canada that sells them. Pyramid air no longer ships into Canada. Which sucks because I used to get lots of my airgun parts from there. Easy when you just go down every now and then.
EDIT: BTW DON'T SHOOT YOUR FRIEND WITH THIS THING! It will F***ING hurt him REAL bad.
