Does anyone know how to make loud explosions from fireworks?

Does anyone know how to make loud/big explosions using fireworks that you can buy at firework stands?

I only know 2 ways, but they arent as good.

Special sparklers. wrap them up as hard as possible and they make a big bang, for the last few years i cant find those sparklers anywhere.

Other way is using picolo petes, you crush the powder inside with a hammer and light her up, instead of whistleing, it makes a loud bang.

any other/better ways?

 

I am not sure if anyone here knows more about it than you do?

 

I had visited some fireworks factories and talked to the staff .
The way you mentioned is right .
What you need to do is to wrap them as hard and tight as possible .
So the next step is finding some sparklers .

 

Loud explosions? Just light 30 of them all taped together at the same time. I bet that would work

 

I know, but i want something that could make walls and cars disappear. if you know what i mean...

 

get a dynamite instead...that would literally make the walls and cars disappear why would you want to make one anyway?

 

For fun. I was thinking of making a little video, thats why i need something big but not deadly.
