The Pendulum

Foucault Pendulum

For my 3rd grade science project I created a pendulum using a ladder and a two-liter soda bottle. The soda bottle was filled with elmers glue mixed with food coloring and then set into motion. As the pendulum swings back and forth large sheet of butcher paper underneath the ladder reveals the movement pattern of the pendulums motion.

In addition I setup a display covering the different types of Pendulums and my source of inspiration, the movie "The Pit and the Pendulum". Definitely my favorite science project over the years and one I'm eager to share with my son when he is older.

Barry's Response - Yes John. Pendulums are neat things. Especially the device devised by Léon Foucault, depicted above.
