Introduction: Non-Lethal Anti-Personal Device/Tactic

Plastic ball bearings can be used as an anti-personal device. Theyt can be used to deter everything from mobs to single assailants. The caster can use cramp ons, cleats, spikes or golf shoes to avoid the bearings. Recovery can be made using a wet dry vac or leaf blower in reverse.

Plastic "ball Berings" can be had at several dollar stores, toys R Us, some hardware stores, and higher-end fish stores(they call them bio-balls, and are used for a filtering media) The "technique" works best on hard, flat surfaces, like concrete... a gravel or soft dirt driveway would just eat up the balls. Bonus points, if you figured out that METAL ball bearings work better. if you were bound and determined to Go BACK THE WAY YOU JUST RAN FROM, you could use a magnet to retrieve your metal marbles(yeah, remember your mother telling you to pick up your marbles, or you'd break your neck?) Added bonus, if kept in a bag, you now have another defensive weapon(provided you haven't thrown them on the ground already). As with any other self-defense technique. you must practice, and executee almost on instinct, or you're better off just running a little faster! Caltrops have been used in a similar manner for centuries. and to great effect. Police even use spike-strips, a specialized form of caltrop, to attempt to stop highspeed car chases(though, with runflat tires becomming more common, that may fade into history) - several million points for poor thinking though. the poster has obviously never tried WALKING much less running, with crampons on(or cleats, or golf spikes) on the type of surfaces where this'd be effective. I'd rather have running shoes than cleats, and marbles anyday/night.

" my spine is tingling at the thought of the sound of crampons on's worse than fingernails on a chalkboard

Carry a thick rubber band and use it as a sling shot.

This is a forum topic, and should not be an instructable. I guess this would work, but i prefer a blowgun :P

Though my memory isn't as fresh as it used to be, I can't ever recall any instance where I've simutaneously been : standing on a flat surface, holding ball bearings, whilst wearing crampons or golf shoes, and an urgent desire to escape person(s) in the immediate vicinity. In fact, I'm more likely to end up standing on the damn plastic ballbearings myself, and end up skating across the floor like some crazed ballerina. I may still escape, but not with my pride intact..

if u add some oil u might avoid them from bounce n stick on the floor quicker and double slip ... that surely has to be painful o better avoid places where u shoulda not be ; )
