Would You Turn It On?
If you flipped an old clock over, only to see “miracle eye – on or off,” what would you do? Would you turn it on and hope for the best? Or do what this Reddit user did, and ask the internet for advice? Luckily, they got their answer.
The switch is a light sensor that can be turned on and off. When it’s on, the clock doesn’t make any sound unless it detects light. This is used for sleeping to make sure it doesn’t wake people up during the night (via Everyday Monkey).
