not as elaborate as some of these pvc monstocities, but still fun to make.
Step 1: Materials
machanical pencil or spring loaded pen
car or tv antenne
hammer or blunt metal object
Step 2: The Barrel and the Grip
first, take apart your antenne and find a cylinder that almost fits your bb
then hammer one end so the bb can almost get through but not quite
(you may have to trim it down so you can use the trigger later on)
Step 3: Trigger (simple)
find another pipe that is narrower than the barrel
flatter the very edge of the pipe like this ______________>---
(sorry, my camera sucks)
Step 4: Firing
load your bb into the barrel and ley it go to the end
then load your sring the same way
now, insert your "trigger" and push agaist the spring untill both the bb and the spring fly out and hopefully hit somebody you dont like
Step 5: This Part Sucks
now the hard part is finding you spring lol
unless you solder the spring to you "trigger pipe"
MY TRIGGER IS AWFULL! Any sugestions would be great.
this was my first instructable so be nice. l8r :)
