A Burna Bottle is a primitive Ork grenade similar to a Molotov cocktail that is beloved of Ork Burna Boyz. These simple and brutally effective weapons consist of a glass bottle -- or occasionally a clay pot, in the case of Snakebite klan versions -- into which is poured volatile Squig oil, filched promethium, and anything else the Greenskins can think of that has a high probability of catching on fire.
Burna Bottles are extremely popular weapons among the Burna Boyz who frequently compose the crews of the Ork attack vehicles known as Boomdakka Snazzwagons.
