Zombie Weaponry

Here are some ideas for some home made anti-zombie weapons:
1. attach an air horn to a grenade and chuck it
2. nail the handles of 2 cleavers together so the handles overlap but the blades don't and face opposite directions, and throw it
3. put a time bomb inside a large piece of meat and leave it in the path of a herd
4. canned zombie scent ( http://geniusideasandstuffiwant.blogspot.com/2011/09/zombie-scent.html )
