Yes if you make it strong enough. If not it may shoot right at you

Well enough for the short time that the gas will be in there

But generally this is a pretty bad idea. The right way with PVC would be to use a screw cap for the opening and glue the rest. People have been maimed by shards of PVC but generally the propellant (butane or propane) doesn’t make an explosion that powerful. If it’s badly sealed you’ll get a small jet flame wherever the gas can escape, so watch for burns.

The cool potato canons use acetylene (from calcium carbide and water) but you don’t want to ever do that with a PVC cannon. If you’re doing carbide then it should all be welded metal tube, you weld a big nut at the rear and use a screw to close it off after you put the water (or gas). I repeat never acetylene with PVC you’ll blind yourself or worse.
