I have a friend like that! One time during winter and with everything covered in snow, we got the idea to pour a trail of gasoline across the front yard and light it. Well, of course gasoline is lighter than water, and as the flames melted the snow, the gasoline began to spread across the yard on top of the melting snow. It took some pretty frantic stomping to get that one out!An entire gallon of gasoline poured onto a pile of leaves will create a mushroom cloud and singe the eyebrows off of your friend that you talked into lighting it. It will also still make you laugh at the memory nearly 50 years later.
