Mylar/Helium - Edit2

[vagabond]

Glitter-blue, a cartoon star      "everything´s just a ride" is what I get later from this image - a good line to begin this poem
birthday helium balloon
wrinkled, half-inflated
crosses six busy freeway lanes 
low, cat-played                           I  get that being cat-played should show the balloon´s movement (and it does, nicely!), but I still mostly think "boom" in this image.
by unsettled crosswinds.
 
Mylar abides forever
unbiodegradable;
helium, like hydrogen       in my opinion the comparison to hydrogen is unnecessary
but less so, contrives
escape from all confinements.
 
As between flesh and spirit
meme and material
which is Mylar and which helium?       
Flesh escapes, evanesces,           
recycles after giving
life its declining lift
but meme and spirit
though they rest and tatter
seeming empty or forgotten
nonetheless endure.                   maybe I get this wrong, but I don´t know if I want my spirit to be eternal if it must endure empty and forgotten.
 

the gas actually is way longer lasting than any human-made material… its escape does  not make it vanish. well it may be changed in nuclear fusion but it´s a long way to the sun.
you said yourself what our bodies are composed of recycles.
 our flesh is only held together by the fact that our bodies are alive… but individual life is not eternal (like mylar is not, it´s flammable).
I like your metaphors, though I´m not sure about the spirit part.. I think it´s either somewhere with the helium or not.
