With fireworks being legal in Iowa, expect to see videos like this becoming more common. Although I don't think the legality is an issue with idiots messing around with explosives.

Many of us will be out celebrating our nation's independence by recreating that "bombs bursting in air" bit from the "Star-Spangled Banner." Then you have the pyrotechnic genius that are just looking for things to blow up.

That's how you end up with a video like the one below. This guy lit an exploding firework of some kind in the trunk of his VW and closed the lid. Needless to say, it did not go well.

Such was the case when this man lit fireworks in his VW and closed the trunk lid. It didn’t go well.
