Potato Cannon Rifle Prototype

this is a work in progress, but it works as a somewhat faster reloading potato cannon as of now. the goal is to make it pump action or soon semi automatic. im putting up this early version so others can give input and advice or start their own.

it is made from a simple combustion potato cannon
modifications- * indicates that the modifications are finished and included
valve for aerosol input*
valve for air renewal
slide on barrel*
cartridges*
clip
handle w/ ingnitor

currently the "rifle" fires a potato but when next potato is loaded and ready to fire there is not enough oxygen in the combustion chamber for the aerosol to ignite, or the barbecue lighter im using as a trigger to light. i plan to add a fan and another valve to the back to push fresh air into the combustion chamber
