Came up with this a while back. It's very simple, but works great and makes missile launchers so more amusing. 1. Get a figure that launches a missile(duh). 2. Gets a small rope of some sort(Cotton twine works best). 3. Then, tie the missile to the launcher! Make the rope longer or smaller, depending on how far you want it to go. And voila, you have your own makeshift grappling hook launcher thing. Another thing I like to do is to use clear plastic bands to tie various small weapons onto the missile. Another good thing about this is it that it prevents the missile from flying out somewhere and getting lost.
