I was just awoken by a great crash! At first I thought there was an intruder! Then I thought I was having one of those waking-up hallucinations. I looked around and turned some lights on. I went into the kitchen and look what I found! This was sitting on top of the fridge and made out of very thick heavy glass. It was holding a bunch of coins. It was "holding up" a thick cookbook in a stack of cookbooks. Well gravity must've gotten the better of it finally since the book was fallen forward laying nearly flat on the top of the fridge! Now I'm scared to go back to sleep! I can hear the birds chirping outside my bedroom window. See photos. I don't know if you can tell how thick that tall square glass jar was or not. Btw this happened almost exactly at 4 a.m. It's now 4:25 a.m.
