ya, cardboard is pretty incredible... They make model rocket cassings out of it. Granted they use much thicker rolls, but also they are dealing with pressure, and assuming you don't drop a steel weight down your barrel or add a burst disk, the pressure isn't going to go much over 3psi anyways.

Do not look back, and grieve over the past, for it is gone;
Do not be troubled about the future, for it has not yet come;
Live life in the present, and make it so beautiful that it will be worth remembering.

This is not the first cardboard cannon:

That one even works with ammo.

But it does show that the cardboard can more or less hold the pressure.
Cardboard cannons are simple, yet amazing projects.
