How to make a Pull Pin Fuse

I make a spring loaded pull pin fuse. It is a very simple pull ring fuse that can be used for air-soft grenades or have a time delay added to it. It works like a strike igniter. The one I made still works even after a piece is broken off. It can also be made with better materials so it will not brake. Blog: Twitter: Music by: Kevin MacLeod Track: Willow and the Light
