What's up with KWA's BBs?  I shot some .25s out of my MP7 (which was then stock) in early fall, they bounced off the wall and a bunch landed on my deck.  After I took the trash out today and I went to look at them out of curiosity.  They're still very smooth.  In their current state they're probably just as good or better than most other brands.  So, what's with these?  I just find it strange they haven't degraded a little, or scratched, or anything at all!  They seem like they might be a hazard to outdoor fields.

Well, they are not biodegradable nor are they sold that way.

Well no plastic BBs are going to be good for outdoor fields unless they're biodegradable. Every outdoor field in Oregon requires the use of biodegradable BBs for this reason.

I think the confusing part would be that plastic has a tendency to become brittle when exposed to direct sunlight for an extended period of time... I would expect the BB's to break apart when stepped on. However, the polishing process looks to prevent the natural decay from the elements...?

Maybe, then again do you know how long it takes to beak down a plastic water bottle?  450-1000 years unless it's made from PETE (Polyethylene terephthalate) in which case it will never biodegrade.

Want a multibillion dollar idea?  Come up with a bacteria that will consume plastic...

Wouldn't it be much easier to just push all the plastic together and melt it down with acid or whatever?

Yea, I am aware of how long it takes to breakdown plastic water bottles. However, BBs do not appear to be made of the same plastic. Based on the shattered BBs I have seen, they look to be made of a denser plastic that becomes brittle when exposed to the sun (baked) for a significant period (months) of time.

*Side story*
When I was younger I had an oversized plastic Nerf bat, I left it on the ground outside all summer on a dirt patch on the sunny side of our house. When fall came the baseball bug bit me again, when I tried hitting a waffle ball, but the bat exploded into a dozen pieces upon impact... like it had been dipped in liquid nitrogen.
