i was wondering how can you make the loudest and strongest shockwave which you will feel in you chest and travels like far if i shoot it across a river like 1-2km on the another side they will hear the explosion like for example a ethanol combustion cannon where you get a pvc pipe a tomato can poke holes in the can put it in the pvc pipe close the other end with a bottle you spray ethanol in there then light and it creates a boom and a shockwave which i think is cool so is there alternative ways if not better ways to make loud shockwaves at home like them??
and it has to be actually strong not a spud.
