Thumping thunder cracker

[Pyrostar]

Hi

I made my first thumping thunder cracker, it contained a greeen star, 0,8g KNO3/Mg flashpowder and
it was recorded in front of dikes, so the report didn´t seem so loud.

That is the video:


I was quite surprised, because it was very loud for such a small amount of KNO3/Mg.
The KNO3 was airfloat, the magnesiumpowder has got roughly 100meshh, it is homemade with a sanding disk.
Maybe I will post another video, because I have made a 2g thunder cracker

I hope you all like my cracker,

Regards,

Pyrostar

Woah that was a real nice cracker you made there. I especially liked the green before the bang also the delay was not to long. I would like to know what the composition is of the green flame?

Hi

The star-composition is listed in the PFP database.
And yeah, the green was very bright and deep.

I will make another one,
