From M.o.1 -- I am VERY pleased to see the GWTF crew showcasing this aspect of using slingshots as a weapon. I have been working with members of my school with using slingshots as viable weapons w/ a variety of different projectiles. Most of the projectiles that can be used can be made by hand very quickly. Projectiles such as:
*Steel shot of varying sizes for a variety of different results upon impact
*Paintballs(used for blinding when aimed at the face)
*Pepper shot (improvised munition which is basically equal to getting his in the eyes w/ pepper)
*Sand/glass shot (very similiar in contruction to the pepper shot only more deadly)
*Explosive shot (works exactly as it sounds)
*Arrow launching (adding a whiskerbiscuit arrow rest w/ some cable ties = compact bow)
Of course you can also use common rocks as well. For me, I tend to follow a more "point shooting" aspect when it comes to slingshot shooting but really it just comes w/ practice.
Enjoy this demo!
