Note: Video is after the jump because I couldn't live with myself if anybody accidentally put an eye out on the front page.
Jack Streat went and built himself a fully functional Lee Enfield sniper rifle out of LEGO Technics. And by 'fully functional' I mean the thing can accurately shoot LEGO blocks up to a couple feet. It's definitely not gonna make a terrorist's head explode or anything. Now I'm not saying you could do more damage with a Lincoln Log catapult, but I have eaten a couple LEGO bullets before with little to no damage (they passed just like corn except with a *tink* when they hit the bottom of the bowl).
Hit it for a video demonstration of the plastic pews.
Thanks to T.J., zygomatic arch and jenn, who were all sent to the principal's office for making guns out of popsicle sticks during arts and crafts.
