✨ Sundials once served entire civilizations as the only means to tell time! 😮
🏖️ If you go to the beach with the family and pitch your umbrella in the sand, you can get a basic understanding of how sundials work. As you enjoy the afternoon by the ocean, you may notice how the shadow your umbrella casts on the sand changes throughout the day. Without even looking at your watch, you probably know when it’s time to head home by where the Sun is in the sky and the position of your umbrella’s shadow. ⛱️🌊🌌
