Puzzle: Bang, Boom, Bam & Pow

I am not patriotic in any way, but I do love fireworks [I know there are many who don't like them for very valid reasons, but, for me, they are one of a very few parts of my childhood that I am not ashamed of. I grew up where they were legal and sold and shot for every holiday, not just the Fourth of July. My grandfather liked them very much. My sister engaged in bottle rocket wars, holding them in her hands twisted in configurations, against the neighbors.] I bought a dubious box of sparklers at the grocery store weeks ago. We'll see how they go tonight when it's dark.
So here's a 500 piece, Charles Wysocki, called Bang, Boom, Bam & POW. Very easy. I got it for today.
