A Real Breakthrough!

The only small, portable Foucault Pendulum on the market!

The Science Design Foucault Pendulum is the first practical Foucault Pendulum for the classroom. Using a patent pending design, the Science Design Foucault Pendulum combines an energy pumping system with a mechanical framework which balances and isolates the pendulum from interfering forces. The result is a unique classroom tool which can be used to investigate and prove the rotation of the earth.

As the World Turns...

150 years ago, when the first Foucault Pendulum was swung, it was a marvel to behold. People would wait for hours to get in and see the experiment that showed the Earth turns. Some would stand there for hours (some still do today) just to see the direction of the swing slowly change throughout the day.

Why did it continually change direction? Since the pendulum wasn’t being turned, people could see for themselves that Earth itself must be the one rotating beneath it.

For 3000 years people argued whether the Earth or the Sun moved and why we had day and night. But now we know unequivocally that it's the Earth that turns and you can prove it with our Foucault Pendulum. The New York Times® called the Foucault Pendulum one of the ten most beautiful experiments of all time. Now you can have one of your own.

Patented Energy Pump

Like a child on a swing, the Science Design Foucault Pendulum utilizes a microcontroller to add energy to the natural movement of the pendulum at just the right moments of the swing. This allows the Science Design Foucault Pendulum to swing for weeks to months.

Easy to Set Up, Use and Store

At four feet tall and under 10 pounds, the Science Design Foucault Pendulum is durable, portable, easy to store and compact for travel. Using a modular framework, the Science Design Foucault Pendulum can be assembled and disassembled quickly and easily. A power supply, windscreen, instructional video and lesson plans are included.

An Exciting New Tool for the Science Classroom

The Foucault Pendulum is the first non-astronomical experiment to prove that the earth rotates. Now with the affordable Science Design Foucault Pendulum, teachers can demonstrate age old questions in the classroom such as why the sun moves through the sky and how do we know the earth is really spinning.
