Sundial watch
In the time of the bedrock,how was time told?There was no electricity for watches.So they used the sun to tell time.The sundial watch was invented on that day.The sundial watch works like this:You take the sundial watch,put it in the sun and look at the shadow.Did the shadow move after an hour?If you want to know,you must do it yourself and tell if it worked or not.
