This is a TNT cannon which count as a rapid fire TNT cannon, because of the redstone clock next to it. I've been exploring a lot a different 1.10,2 cannons, but this one was the one which best works. The others, (I've tried multiple times) don't work, so enjoy this EXTREME cannon. If you want to use this cannon for your own reasons you may, but if you will do a youtube video about it, please mention my channel. My channel name is EpicHype. I hope you enjoy this!
