Boom!
The can of petrol fell on the grass nearby as the petrol from it leaked out while the fire spread accordingly. The heat caused the air within the can to expand and make it explode, splashing out the petrol in the vicinity.
And with that, the fire caught on. Immediately, the grass wriggled, moving over in an effort to cover the fire and snuff it. But as this was a fire created using petrol, it wasn't easy to stop it, especially for the grass that began to fume immediately.
The moisture in them began to vaporise from the heat while the oils within them got ignited in response, further fuelling the fire, causing its temperature to increase.
"Alright, we have a chance!" Saying so, Compass Carburettor began to throw the cans and bottles one after another, using his enhanced strength to throw accurately, forming a trail of fire from one end of the flyover till the foot of the hill.
