Today is the Winter Solstice ❄️ Here’s a Science Guy demonstration of what a Solstice is and why it happens a few times a year. If you’re in the Southern hemisphere, enjoy your longest day of the year… and if you’re in the Northern hemisphere, hope the shortest day of the year goes by quickly. Happy Solstice and Holidays to everyone around the world 🌏🌎🌍 #wintersolstice #solstice #science #sciencetok #winter #holidays #happyholidays

We are so fortunate. Science rules.
