In yesterday's garage, hands crafted with care,
Tinkering with valves, like conductors leading orchestras there.
But now, the manual sounds a warning bell,
"Beware, don't sip the battery's poisonous well!"
Progress brings caution, safety's guiding light,
Trading DIY spark for warning signs in flight.

We're smarter, more aware of hidden snares,
Yet lost some innovation's fiery flares.
Valves still need fine-tuning, like a painter's delicate stroke,
But now we know what pitfalls to avoid, like a sailor's treacherous cloak.
Smarter, safer, with caution's steady helm,
A new horizon unfolds, like a map's revealing gem.
