Fireworks

How are the initial solutions prepared (known amount dissolved in a solvent) since white phosphorus is highly reactive to air (pyrophoric) and decomposes in light?

I live on a large lake, so idiots begin shooting fireworks the moment the tent vendors show up; and continue for weeks after the 4th. I heard a couple of bangs around suppertime, so gave Ben* a 1/2-tablet dose of "NaturVet" melatonin and calming herbs. He was happily snoozing by the time it got dark and the true fireworks began. Fortunately, Augie seems fairly resilient when it comes to fireworks, although I'll give him a tablet the night of our huge professional display.
*Ben was 3 months old, when some jack*** shot off a "mortar" about 100 yds from our house just as I had set him on the ground to go potty before bedtime. It scared him so badly that he screamed.... This occurred 3 weeks AFTER the 4th - and imprinted a forever-fear of loud noises in him. Lake life is nice, but there ARE drawbacks - somehow, water draws out the "stupid people factor"

On Saturday, two houses burned to ash and a third was severely damaged. People weren't home, but three dogs died and devastated that family. Stopped counting the number of fires all those fireworks set off in this drought-stricken area.

My writers' group had an assignment, to write a sonnet. Instead of using the more common Shakespearean form, I chose the Petrarchen form:

Fireworks
These angry eyes, o’er which my tears doth burn,
See fireworks sparkle high, their beauty masked
By utter destruction, for as they passed
Their embers fell to spark dry plants and churn
A conflagration. Yet they had no concern
That their fiery trails caused more questions asked.
I wonder, who next shall have that dread turn
When their beloved pets are isotherm?
I dare not retire ‘til revelers cease
The careless unconcern for others’ plight.
I stand with my hose, primed to release
The water and hopefully gain some peace
By slaking the red motes I see this night,
Leaving only moisture upon our street.
