Pendulum Snake DIY, a Build Your Own Exploratorium demo

The Pendulum Snake exhibit blends art and science into a mesmerizing visual display of physics and time—a swinging series of pendulums that reveals a remarkable pattern found in nature.

Learn how to make your own pendulum snake with metal weights and PVC pipe. Exploratorium Senior Scientist Julie Yu shares the instructions for this easy DIY wave project. She also demonstrates the pendulum snake exhibit at the museum.

The project is just one of the Exploratorium’s huge library of Science Snacks, “hands-on, teacher-tested activities that bring explorations of natural phenomena into the classroom and home.”

Each activity uses inexpensive, easily-available materials, offers detailed instructions and images, provides a clear explanation of what’s going on, and is adaptable to a wide range of curricula, content areas, grade levels, and settings.

Pendulum Snake is also one in a series of Build Your Own Exploratium videos that are on their YouTube channel.
