What could have caused this?

[caduceus]

Went into the garage trhis morning to do some work on the Chim and found broken glass on the floor at the back of the garage floor. I picked up a few bits to find out it was headlight lens. Trouble is, both the lenses were on top of the speaker, and neither had fallen off to the ground or they'd be both smashed.
No signs of someone breaking in to the garage, taking out the first of the lenses from the top of the speaker, dropping it, then neatly arranging the glass as if it shattered in situ on top where it sat originally...

I stood there pondering what could have possibly caused this. Could the magnet in the speaker have reacted to the reflector which sat on top of the top lens (which shattered) and caused it to shatter!? This is the only bizarre reason my clouded mind can muster.
Here is a video of said scene:

Temperature fluctuation making a pre existing fault in the glass fracture?

[talksthetorque]

No Idea, but I'm thinking of doing a justgiving page to get you some new gloves.

Possibly. But there hasn't been enough of a drop in temps to cause that I don't think. But then I'm no 'thermologist' or whatever geek terminology it is.

And yes Torque, if you could that would be most kind.

THere is a type of glass that can spontaneously shatter. Not sure if that's what would be in a headlight though.

Some kind of force acting on top of the garage pushing the roof down and causing the headlamp to be crushed between the roof and the top of the speaker?

Poltergeist activity. Have your garage exorcised asap.

Note: If you don't pay your exorcist you may be repossessed. ( apologies to Goodwood Revival 2015 )

Did what exactly? Managed to shatter the top lens and push a few bits on the floor for good measure?

I'm guessing it's something like this or along the lines of it. There is no other explanation other than it spontaneously shattered and some of it flew onto the floor.

Not cats, mice, birds were in the garage and I shut the door almost immediately after opening the door and turning on the lights.

Is your car called 'Christine'?

[poing]

No idea but Steptoe would be very proud of those gloves.

Would you like a matching umbrella?

yep. Half bird, half mouse, half rat. Couldn't be anything else.

Typhoon Doris swept threw, felling trees and breaking headlight glass hither and yon....

It wasn't....

I'm guessing you've had condensation in the light unit pooling and during the recent cold snap it has frozen and expanded shattering the glass,
Of course all evidence will now have been lost
