...what happens when you accidentally hit the side of your oven door "just right" with a glass measuring cup, this is it:
If you think you are looking at one million pieces of shattered saftey glass, you're not. You're looking at 10 million! And the circular space on the front left corner area is where my naked foot was during the rainshower of glass. Delightful!
As a side note, the glass measuring cup didn't have so much as a chip out of it. Go figure!
