This happened in Brazil. It’s home security video of a guy and his two dogs in his backyard . . . and he’s flicking lit matches onto the grass because he’s trying to burn a cockroach infestation. But when the grass ignites, the lawn explodes.
Luckily, nobody was injured, including the dogs. According to one report, he lit the matches AFTER he sprayed the area with insect repellent AND gasoline.
