Do-All Outdoors Thunder Cap
Just screw the Thunder Cap onto any standard plastic soda bottle up to 2 liters. Then get an air pump (not included) and insert the pump needle into the Thunder Cap valve opening. Pump the bottle with air (no more than 100 psi.) You can add some colored corn starch or flour to give your exploding target a visual report.
Then let your arrows fly for a fun, loud, and explosive target shooting experience!
