Hemp soft, Pea soft

I'm not sure how it is in other parts of the world, but in america, getting toy guns and shooting up your friends is a sort of rite of passage among many groups.

Guns firing corks, peas, and bb pellets were popular in their time. Squirt guns continue to sell well, and today, airsoft pellet guns, or paint balls, are the weapon of choice.

Air soft pellets (Which are neither soft, nor air) are easier to clean up, but anyone who has walked about our cities much will notice a few plastic balls, about the size of a pencil eraser, left in the cracks of pavement, and in other places. These airsoft pellets are not biodegradable, and will likely become some sort of problem down the line.

"Biodegradable" airsoft pellets exist, but if they're anything like the bidegradable clay pigeons, the process will take a long time, and the results are not particularly promising. In all reality, iron is probably just as biodegradable.

I propose a recreation of pea shooters, which can fire peas, hemp seeds, corn seeds, or other approximately rounded seeds. Since seeds are biological, they are biodegradable, and since they are seeds, they are often either eaten or germinate into plants.

Individuals interested in shooting each other with such weaponry will likely develop some interest in growing their own ammunition, thus allowing for a greener warfare.

But wait: I see you arguing already that this cannot possibly work, because seeds are not entirely round, and this will effect range, and accuracy.

Seeds can be coated in biodegradable resins to make them spherical. Pine pitch for example. Or tar. Yes, thick enough tar will remain quite stable at room temperature.

However, another possible expedient also presents itself: A Silicone barrel would likely work rather well to make up for any imperfections in the ammunition.
