TAOFLEDERMAUS decided to go big on this unique experiment.
Watch this video and see this improvised giant shotshell hurl inflatable balls high into the air.
This video shows quite an impressive homemade super shotshell.
All of the regular shotgun shell components are there that are usually needed, though significantly larger. The bucket is the shell, Tannerite is the propellant, and then the wadding and the projectiles are inflatable balls, in this case.
