Then there's this, still not interesting...

When I was about 9 yrs old, our parents bought a new house. Among the things the previous owners left in the garage was a large glass punch bowl and 8 matching glass cups.
I was fooling around with them one day, and I accidentally dropped one. I lunged for it, but I was too late -- it hit the concrete garage floor. But the weird thing was, it didn't break -- it must have hit in just the right way, because instead of shattering, it bounced, and I caught it in the air.
I was astounded -- I'd never heard of such a thing (and I've never seen it since, either). So naturally, I called my brother into the garage, said "Hey, watch this!' And dropped it again. This time of course, it shattered into a million pieces. I swept them up and didn't tell anyone what happened, until now.
