Tutorials/TNT cannons

TNT is an explosive in Minecraft. Using that, Water and redstone can be a deadly combination. These cannons can be designed in different ways, some are made for long range needs, and there are some that can shoot in multiple directions. Like this one:Tutorial by TheWarlemming

There also other entities in minecraft that can be propelled by tnt such attaching arrows to one of the projectile Tnt to rain arrows down the fields or even attaching arrows to the booster Tnt them self to propel multiple arrows at an target which has several advantage over the dispenser/arrow turret traps such as propelling several arrows at the same time without large scale redstone circuitries and a large number of dispensers, but cost more due to the cost of tnt and can be dangerous if executed incorrectly, and needs manual loading after every salvo.
