Our Fire Dept. responded to a call of a possible house explosion. The residents in the area all stated that there was a loud explosion and they thought for sure that it was a house explosion. After driving up and down the roads for what seemed to be 15 minutes, an ambulance crew from came across something unusual and asked us to take a look at it. We had a State Trooper with us, both he and I figured out that it was firework related and we called separate contacts on bomb teams. His contact told him about the use of sparklers to make bombs. We used the Trooper's cell phone to go online and look it up on Google. Sure enough it is exactly what we had. I have included several photos for your viewing. This one was fairly harmless since it was lit in a open field. They had placed it in a plastic bag of packing peanuts and lit it off, and it blew the debris over a 20'+ diameter, but remember the sound was extremely loud. I would encourage you to Google sparkler bombs and view some of these videos. Some of them have included placing the bomb in a washer machine and blowing it to pieces.  They take sparklers and wrap them tightly with tape and then use one sparkler for a fuse. The more sparklers they use the more damage it creates. I thought it might be helpful to share my experience with everyone.
