It was 5kg of my recently developed C14.6-H liquid explosive composition boosted by 60g ANNMAl and detonated with 0.2g Ag2C2.AgNO3. It is an ammonium nitrate based explosive solution with 15% water and off course some other stuff, no glass balloons, no other self explosives, no metal powder.
It is the easiest and cheapest (10% cheaper than the C14-H) explosive to make besides ANFO, the good thing is that I can use low quality fertilizer grade AN in prills, and allow it to dissolve by itself, no need to dry (off course it is a liquid composition with water) or powder; it is so easy to make that it is possible to fill a swimming pool with it in a few hours. The down side is the power, it is stronger than ANFO with a higher VoD but weaker than many other compositions I have made.
The video really don´t show the real sound of the detonation, it was very intense with several echoes, the last one I heard strong happened 30 seconds after the detonation so the sound travelled for 60 seconds before it got back. Some people about 2km away thought that there was some rock blasting operation going on in the area.
