How To Make a Canon Minecraft TNT (4/9 steps)
Step 4: Setting up DTT
As seen in the picture above, the TNT will be placed along the stream of water and a TNT on top of the carpet. Do not forget !: Never PLACE TNT in the SOURCE block of water, this is just going to make your Canon explode as the water will later flow through the TNT surfaced, which he can not do if you Remove the source block. I also have a tutorial for the same concept just with an automatic look following this, if you liked my first tutorial then definitely peek as well and maybe take inspiration.
