This is a very fun project for kids i know because im 13 girl haha but caution this is not for little kids because it is still full of ink and is sharp if they shoot you
Step 1: Materials
Materials: office pen Knife or Xacto knife Rubber band Tape
Step 2: Step One
Ok now take the pen and take it apart( dont break it though)
Take your knife and make a hole that goes through the pen.
Now line it the holes up with the ends of the pen after u do that make a indent so we can place the rubber band there later
Now, take the rubber band and cut it so its just one line
Take the rubber band and put both ends on the indent marks make sure they wont get loose and make sure to make it stretchy so its not loose.
Now tape it up
Now take the pen ink part and put it through the holes and there you go pull the rubber band back and shoot
