So now seriously, how to build a minecraft cannon? I saw a lot of videos, showing how to build such a cannon and stuff. However, I don't get to get it working. I mean, I can build it with 1-2 rows TNT and it works fine. But sometimes, just if I take too much TNT (3 rows á 4 TNT for example), it blasts the cannon and I can start to build it again.
If any of you folks know exactly how to build a decent cannon, tell me please. I don't know why it doesn't work.
Greets and out.
