You're stuck on a island with no sign of human habitation except some litter bobbing at the shoreline. You need to hunt the wildlife for food (or, if you're a vegetarian: there's a vicious critter (or coconut) stalking you, and you must kill it).
What do you do?
Construct a make-shift sling out of a plastic bag!
My goal was to create a reasonable sling out of a plastic bag using the simplest possible construction.
It's not all that accurate, nor powerful, but you're using less than half a plastic bag.
You're getting quite a lot out of this little scrap of trash.
- A plastic bag (grocery bags work well, but some of the classier, thick mil bags won't)
- Scissors (also useful for close-quarters combat with that vicious critter!)
- ... and some bandages + first aid cream (see step 5)
2 x ropes from twisted strips of plastic
1 x cradle from folded rectangle
1 x finger loop
Project takes about 10-20 minutes, possibly less.
Don't poke anyone's eye out, don't strangle puppies with the sling. General safety rules apply, but by and large, this sling is a rather tame weapon. (I think you need to be more conscientious that your left-over plastic isn't a choke hazard than over projectile injury.)
Honestly, I'm more likely to use this to lob crumpled paper at my friends than anything else, so I'm blatantly ignoring the "don't shoot people" rule.
