Expanding foam like this uses 2 chemicals reacting with oxygen as a catalyst. While definitely possible to create, I would highly advise against this in a DIY application. In my very limited exposure to paintball, I have had some burst paintballs in the hopper and in the gun itself.
Can a paintball be filled with expanding foam and still work?
Regular paintballs work just fine. Or so I’ve heard.
