H most certainly can ignite
Much the same as dynamite

But any flame needs O2 to burn
This is the beginning of my concern
O2 with H, a dangerous mix?
Instead its starts to play some tricks

Too tight is the bond of H2O
So now we know it cannot blow

Unless of course, electricity
And really this is a necessity

To break apart this liquid life
As if to cut it with a knife

Two H one O come out to play
The poor O must wait, must stay

It cannot burn it is in trouble
Unless the O is to double

Without the two it cannot complete
Its truly amazing combustion feat

A spark, a light, some heat
Ignition is now complete
