mini weapons of mass destruction: build implements of spitball warfare is the follow-up of john austin’s “cubicle warfare: 101 office traps and pranks” and “prank university: the ultimate guide to college’s greatest tradition”. his new book contains detailed step-by-step instruction with illustrated pictures to build over 40 types of mini weapon using household products and office supplies such as binder clips, paper clips, pencils, clothespins, rubber bands, spoon, matches, etc. this is fascinating, i have to say.
