A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction…

The ball is placed on top of the acrylic square, which is positioned on top of an aluminum post. The spring is pulled tight and then released which shoots the square out from under the ball. The balls falls into a concave recession in the post. Similar to pulling a tablecloth out from under a set…
