Feeling bored? This great addictive shooter will keep you entertained. and the great thing is, you can make it in 5 minutes with some dead cheap materials. you can just aim and shoot it very easily. feeling sick? on the bed? if you have this, with more darts/bullets, you can play with it in the room itself with a dartboard (or just soft styrofoam painted like a dartboard temporarily). Note: as the bullet/dart has very pointy ball point, it is dangerous to all living beings. so please don't hurt anything or anyone with this. instead, show affection to them. And this is pocket sized. so you can bring it anywhere, anytime with ease and also gift it to your favorite person who always falls into boredom.

Step 1: You'll need these.

This project is so easy, that I use the slingy to play, then remove the slingy's parts and assemble the pen's parts and work with it.
now let's come back for the materials.
1) A ball point pen, should be unified in shape and the tube should be hollow if all parts is removed.
2) A flexible rubber elastic band. Should be thin but strong.
3) Two stapler pins. one is used here. second one is for the time when first one wears out.
4) A duct tape.
