While it was path breaking, brave and a novelty at that age, it's totally different now - You don't have to convince anybody anymore that the earth actually rotates around the sun!

Standing 38cms tall, it is an exquisite piece that would make you gape at its work in awe. The Foucault's Pendulum is a simple pendulum apparatus with a sand bath at the bottom. When you set the pendulum in motion, it goes about marking lines and curves on the sand. While it may not make much sense to you in the beginning, take a look at it after 5 minutes or so, and you're sure to marvel at the geometrical designs that it has come up with!
