Hi. It has been awhile since I have made a blog but finally I have internet good enough to load websites. Anyway. I built a TNT cannon ( I love TNT cannons.) and played around with it. Now it may seem like an awesome weapon for a PVP/survival server, it reall isn't that good unless you have an un climable bedrock wall with one door. They only fire in one spot. The only adjustment you can make is differing the amount of TNT used for launching. and even then you still never know where it is gonna go.  And there is also the risk of messing up, all you have to do is place one tnt in the wrong spot.( Pictured Below) In the end I think TNT traps are more effective, and about just as safe.
