I have a wall clock above my tv in the living room. I depend on that clock. It is the only clock in the room. Yesterday, I glanced at the clock, and the minute hand was going backwards! I just gaped at the clock and watched for a few minutes. It went to the 12 and then went backwards for 5 seconds. Then, it went forward again and went to the #1 and then went backwards for 20 seconds! I yelled at hubby and daughter to come and watch! The three of us sat there and watched the crazy clock do it’s acrobatics.It was really amazing to watch. It would go forward 5 seconds, then back 20 seconds and then forward again! It was really cool to watch it go backwards! LOL By this morning, it had lost 30 minutes in time. So, we spoiled the fun and put in new batteries. No more crazy phenomenon. It was cool while it lasted!
