Mumm… there’s a hardware store on the way home that sells all the parts I need to build these uber nifty mousetrap tripwire mines. Very harmless (even if you do put roll caps in them) and easy to make these booby traps could mean and end to office desk pilfering. If you have a bag of these mines, a couple of micro-claymores, and a few Nerf guns you would be all set for a very un-productive day in the office
