From Floaty Friend to Fire Hazard in Seconds

A Calm Sunday Turns Into Chaos

It was a perfect Sunday. The kind where sunlight spills through the windows just right, birds chirp like they’ve been paid for it, and everything feels… still.

Except for our Mylar balloon.

Silver, shiny, and star-shaped, it bobbed lazily around the living room, left over from Emily’s birthday the week before. Nobody had the heart to pop it. It had “You’re a Star!” printed on both sides and floated with a sort of quiet optimism, like it truly believed it belonged there forever.

Unfortunately, the whole house fan disagreed, and both would meet like bumpers in a car accident!

The “helicopter style” whole-house fan has a very large fan resting in the attic just above a hole in the ceiling with thin metal louvers. When the fan was turned on, the breeze created by the fan would lift the louvers and allow air to get sucked into the attic. The fan was old, Loud, and unfortunately, not designed with a safety grate. It was the kind of fan that whirred with menace, the kind that looked like it might bite you if given the chance.

Like any other day, as soon as the air temperature outside cooled, we opened the doors and windows to cool the house. When the back door swung open and a gust of wind swept through the room, the Mylar balloon did what any self-respecting balloon would do: it floated away with the breeze. It swept across the room, turned a corner, floated up the stairs proudly, and directly into the spinning blades of fate.

Bammmm!!!! WAP-WAP-WAP-POP-zzzzzttt…

Spark’s, arcing, molten hot metal pieces of razor-sharp sheet metal lit up our upstairs hallway like it was the Fourth of July! Included in the chaos, two of my kids were close by in the hallway, we’re screaming like they were at war and shot at by friendly fire! What a nightmare of an afternoon!

The sound was violent and brief. The balloon was sucked up to the louvers, but being a thin piece of sheet metal, the force of the fan caused enough suction to bend the louvers up into the fan. The balloon burst into shimmering confetti, and the fan let out a final electrical surge just as one louver got stuck in the fan blade and locked up the fan and motor, leaving only a scream and a hum of a motor to keep in the children’s memory for a lifetime. 

With a flick of a switch and some hugs, Silence returned. As we look around for damage or injuries, a soft metallic ribbon floated down slowly to the floor like a movie visual effect, as if the last few minutes weren’t a memory enough.

From the hallway, someone muttered:

“…we should really fix that fan.”
