Resonant frequency could do it.
Used to be a guy at Silver Dollar City
that used to do the singing crystal goblet schtick and occasionally one of them would shatter.

Wife's voice would be my guess.

When you temper glass, and don't anneal (release stresses) appropriately, you can cause an issue like this.

Yes, but...

 

In today's world you also have to be very skeptical about somebody's claim that they didn't do anything to it, as well.  This guy has about guaranteed himself a new table from IKEA for free, at least.

If it were stressed still from manufacturing wouldn't those pieces be much smaller?
That looks like a I broke the glass and don't feel personally responsible.

The story said there were ELEVEN such incidents.  I could see eleven people out of the hundreds or thousands who bought the table being negligent, possibly.  In a related story, a few weekends ago in Boulder we rented an old house and the kitchen had been remodeled very nicely.  It seems that everything in the kitchen was from Ikea... cabinets, counters, some of the hardware and even the microwave.  I liked all of it.  Very clean, very basic but not boring and not cheapy-looking or feeling.  Just stay away from the glass table.  :P

Don't fill it with methane.

I had a glass top coffee table explode several years ago.  It happened right when I set down a beer mug on it after KU was knocked out of the NCAA tournament.

Yeah. This is pretty much how tempered glass fails... Fortunately, the pieces tend to be rather favorably shaped from a cutting danger perspective.

This is what I was thinking as well.

Um, tempering glass is kind of the exact opposite of annealing. The entire goal is to create a shitload of internal stress.

Yeah, I should clarify that I realize there is built in stress involved and sometimes it goes wrong.

Usually it's a scratch or other defect. Unbalanced stresses should be evident by obvious warping.

So are we just assuming poor quality or poor-workmanship on the part of the glass?

Glass is neat. When I was in high school, our chemistry teacher used a glass flask to hammer a nail into a 2x4. Then he dropped a nail inside and spin it around to scratch the inside surface and it shattered.

I have seen glass do weird shit before as well.  There was some plumbing problem in an apartment I had like 15 years ago.  They sent some guys over to fix whatever it was and in the process one of the guys dropped the glass shower door.  It shattered all over the floor.  They weren't prepared to clean up glass so they said they would run over to the office to get stuff to clean that up and would be right back. 

 

While they were doing that I was looking at the mess and for the next 20ish minutes I watched the glass chunks jump seemingly on their own.  It was sortof like watching popcorn pop.  Random bits of glass would just jump up and down.  Couldn't ever figure out what made that happen

Don't fart into it while hitting the bong and you should be safe.
