http://www.youtube.com/watch?v=EaobxzyPNZU---this gun shoots bout 20 bbs per second thats not a joke...if u make it proprley. when u cut the holes in the cap and the bottom make shure that u use hot glue to get an air tight seal. my container hold about 200 bbs and shoots them at about 18 per second just resntly i made one out of a pill case that shoots 23 but it olny holds 100 . o yeah forgot the most imporent part how to shoot it...just blow threw the top straw dont juge this till you make one ur self.
the first thing u need to do is find a container like this one
then cut a hole in the cover and in the container
like this...make shure the holes just fit the pen
then shove one of your 2 pens in the container hole
then in the cover like dis
this part is very IMPORTANT... to get an air tight seal use hot glue all round the hole and pen.
u can re-inforce the part where the hot glue whent with tape if u want. JUST MAKE SHURE U HAVE AN AIR TIGHT SEAL!!!!!!
