Not sure you would get a good enough seal if you are dropping the unit in like a mortar round should be. There would need to be something to pierce the CO2 cartridge on the back of the Nerf football. I don't think you would have enough weight in it to pierce the CO2.
Plus it would require turning the tube over to get the expended shell out.
I think what the picture intends to happen is that since the Cartridge is sticking out a bit, when you drop the shell inside it will push the cartridge up into the puncturing device thing, then it will push the ball out and I will remove the cartridge.
