DIY BB Gun Will Have Your Room Mate Begging For Mercy

Can’t figure out how to get back at your room mate for stealing the cookies? Perhaps a powerful DIY BB gun might be able to do the trick.

If you’re still confused at how it’ll get your room mate begging for mercy, check out a video of it in action after the jump.
