Bamboo blast tube/ over powered leaf blower

This tool would be used for keeping large groups of hostile mobs at a safe distance by use of a large concussive blast/ large air burst. It would be crafted by puting two lines of bamboo down each side of the crafting table then placeing a gun powder at the bottom center then paper at the top center of the crafting table. The blast would push a small mob such as a zombie about 8-9 blocks away dealing 2damage to all mobs with in the radius of the air blast, the tool will break after one use. I’m baseing this of of real physics, the bamboo acts as a pressure chamber the gun powder produces rapid forming of gases until the paper burst sending a gust of hot air out of the end of bamboo
