deflagrate

Sean John tossed the bauble back into the water, one more round of this aquatic, inter-special game of catch. The shark fin coasted along the surface. The outline of the shark was clear in the flawless tropical water. But as Sean John watched, the sharks body seemed to shimmer. The underwater view was obstructed. Sean John heard a hollow noise. The air seemed to shift. In one horrible instant the pristine water deflagrated. Flames engulfed the shark. The water turned into a roaring inferno. Someone had sabotaged Sean John's sharks aquatic playground.
