Due to the fact that my previous pen gunhttp://www.instructables.com/id/EH4ZKYAVSDEXCFGF1S/
was confiscated because it didnt look real at all and i got caught, i had to make a new one with no givaways. You can see it below. Perfectly normal, well, it looks
that way. This easy instructable will tell you how to make your own classroom-war-waging device.
