Cannon Powder
I've always liked how minecraft cannons were built, but they were always too wasteful and time consuming to be used
realistically. I set out to change that. Cannon powder works exactly like tnt, except it doesn't remove blocks or
damage entities. It's used to push things. I also hooked up the dispenser to spit out live TNT / CannonPowder
instead of just the item.
You can use it to create cannons, elevators, traps, etc.
The recipe is shown in the video.
