Sand Pendulum
Let simple the physics help relax your mind as you stare transfixed at this cool new Sand Pendulum drawing patterns in the sand. Just give the pendulum a gentle push and let gravity and momentum determine the path as it swings slowly back and forth carving elliptical loops and whorls into the sand in the pit. Different start angles create different patterns, so this ought to keep you occupied while wasting away another boring day at the office. Of course, it also makes a unique decorative addition to the home as well.
