on the acceleration of a small shiny object

maybe this is a shout / maybe this is to tell you off, / but if I don't know then how can you / who don't even know why? / I have conquered a sphere of influence, / this is my kingdom / the parallel lines rusty iron stakes / demarcate my rectangle of understanding, / and the life i lived yesterday / preserved in a jar full of chemicals / and shoved out the window this morning; / it gathers force in its fall / I hear a physics teacher blabbing in the next room: / impact -- who would have guessed / that a little penny could reverberate / such a power with the falling / the same penny the soda machine spit out / could explode all the cans / just have to toss it.
