Blivets were developed in the 1960s and 70s. The small package contained jellied petrol which had a small electric match or detonator wrapped around it. They were mainly used as high intensity slash burns and could be wired-up days or weeks before they were required. The blivets were arranged in concentric circuits to develop a large convection column. But the circuits were prone to damage by wildlife if left out too long. DAIDs were also taped to blivets as mini “Molotov Cocktails” and thrown into patches of dense or hard-to-access slash. Small plastic container filled with jellied petrol.forests commission victoria (fcv), planned burning
