If this video is to long I will explain it!Basically the guy took a bamboo cut it and put a shell of gun powder in it!He then cut a little hole at the top and put a fuse!Instead putting a metal ball (Bullet)He put napkins!

If he had put a bullet any sort of metal!Can this be a deadly cannon at all?

Thanks!

Yes.  The muzzle velocity is probably relatively low by modern firearm standards, but it could easily kill you.
