You have seen fireworks mod? If not, don't wory. Because Tnt fireworks are here. I was suprised that I didn't see any post/vids on them, so I guess I created them (I'm , like) I saw canons but i wanted firework for my castle tower on my server. It great for anything. Castle tower, subs special, or just for fun.
use it, make it, share it. and like it.

Here is a vid on them, what they look like and how to make them. Enjoy!

Please do not re-make the video, only with permission, and when you do please link it to the oryginal at the beggining and the end (20 sec in total at least)
