Step 1: Materials (Sorry for No Picture)
You're just gonna need some basic supplies you find at any office/desk/whathaveyou â¢A binder clip (any size will work, preferably medium size) â¢An elastic â¢A pen, pencil, marker or anything that is rod shaped â¢Any type of ammunition (I just used a quarter)
Step 2: Assembly
You're gonna wanna fix the clip and pen like above, then put the elastic over it.
Step 3: Finale
You're gonna wanna put the elastic over the clip arms and pen. Put it over and wrap it around each arm twice. Then voilÃ¡! A finished office catapult. This is my first Instructable, so take it easy on me :-)
