Now I dont want to make an actuall landmind where if you step on it it will explode, but lately me and my frineds have been hearing a lot of btiching about us from this guy we know. We decided we wanna some night dig like a tiny hole in his ground, stick the shit in and light and run. Watch some dirt fly. We dont wanna fuckign massacer is lawn though, we just want something that they wont be able to tell it was a landmine, they'll think someone was trying to dig there lawn up.
Can anyone tell me what firework would work best for this?

Might I suggest a Nap Charge...

you got a site that explains what that is? and how to make?

Here...go to the Pyrotechnics Sections Then go to Naphthalene Charges


and here is the where nick got that from

And here is a thread from awhile back...if your interested

I don't think it would look like somebody was trying to dig up the lawn if you used an explosive...usually when you dig a hole you don't spread the dirt evenly in all directions like an explosive...

If you are pissed at the guy just kick him in the nuts or something...

If you insist on using fireworks/explosives just shoot some rockets or roman candles at him.
