So ever since I moved within a couple hundred kilometers from the Tropic of Capricorn, I’ve wanted to do a particular science experiment. Well yesterday I was able to do it. As I’m sure you know, yesterday was the Southern Solstice. The day when the sun reaches it’s southernmost point in the sky. That means that yesterday the sun was DIRECTLY overhead the good people who live on the Tropic of Capricorn.
So since I took my kids to the pool yesterday at around midday, I thought it would be an excellent opportunity to test and see just how small of a shadow something could have. Check out these pics. From my reckoning, the shadow on the final photo is about 1.5cm long, the stick is about 20cm long, and we live about 300km from the Tropic line. Cool, right?
Check out that shadow! Crazy! Hurray for science!
