We came across this fun project the other day here in the office. I would have to imagine it takes some exact-o knife skill to to chisel into cardboard this masterfully. As always I am positive the video makes it look much easier than it probably is to execute. Very cool and inventive...dare I say environmentally friendly too. Re-purpose some old boxes into a new toy?! Check out the video. There are similar videos with different style guns for those who want to start a paper arsenal.
