Ok, this isn't really a "great conspiracy", but still something to be aware of. I had planned on making up some big conspiracy thing about how it was all related to the Illuminati, Microsoft and Sony trying to take over the world, but guess what? I'm too lazy! So I will just give you the real info, presented in a "lighthearted" manner.

You probably knew this, but TNT Fireworks owns Red Devil, Mad Dog and Freedom Fireworks. But then there is Brothers Fireworks! They had a 12 pack of canister shells I saw on their website that looked suspicious. I looked a bit carefully and noticed the shells were identical to TNT Mortar Fire shell pack I had bought this summer! Then I remembered that in my Big Bad Rambo Canister Artillery Shell pack, it had two shells with Brothers Fireworks labels. This means that the same company that made those shells (4th of July Extravaganza) also makes Brothers Fireworks! And apparently TNT Fireworks owns the whole thing! The master detective solves another one! Score!!!

Update: Apparently TNT does not own Brothers...here is an email I got that should clear things up a little:

Actually, TNT does not own Brothers Pyro., Brothers makes items for lots of other companies, ours included. TNT is owned by what was once American Promotional Events, which was once American Importers, all owned lock,stock and barrel by Anderson News Company of Florence, AL. They also own Books A Million Stores, Hibbett Sports, and Big Lots. They are the 800lb gorilla on our block. Have a good and safe fourth!

Now look at these shells from Brothers Fireworks! They have the same label! The effects listed are also the same!

These shells are made by Brothers fireworks...

...now look at the purple and green shells on the top right! These were mixed in with the 4th of July Extravaganza shells. You can also get a good view of the TNT shells (bottom right) that are the same as the Airhawk shells.

Then I remembered another thing! On the Black Cat Fireworks website in the rocket sections they showed their "Jumbo Rockets" and said, "We have finally found jumbo rockets that meet our high quality standards!" So! That means they don't make them, instead they find them! Suspicious isn't it?!? Score another point for me, the master detective!!! Here is the proof!
