Step 1: Supplies and Tools
For this easy project you will need to take apart a pen and take the pen shaft and the pen cartridge. You will also need a rubber band, a knife or box cutter, and something to poke a hole.
Step 2: Cutting the Grooves
You will need to cut two grooves in the ends of the shaft so you can put a rubber band in it t like in the picture. Also, you will need to cut the rubber band in half in order to do this.
Step 3: Making the Hole
Now with your hole poking device, poke a hole in the center of the pen shaft, and make sure it is wide enough for the cartridge to go through.
Step 4: You Are Done!
Now you can enjoy shooting your very own pen bow!
