For this year's Chevron STEM Zone appearance at the Bay Area Science Festival we wanted to create a new exhibit that would wow the crowd and get visitors excited about science, technology, engineering and math. The solution? Our giant harmonic pendulum, which visually displayed all 4 concepts simultaneously. The design features a 28' x 11' truss arch with precisely placed bowling balls hung on aircraft cable. We accurately mounted several of our kabuki systems on curved pipe to create the release mechanism that puts the pendulum in action. The resulting display shows a harmony between 18 balls with different frequencies whose interactions change through the course of the system period. Scroll down to see a video of the pendulum in action. Other highlights of the 50' x 100' STEM Zone tent included a linker log display created on our CNC machine, our thermal imaging station, as well as several stations hosted by collaborators including Lawrence Hall of Science and The Chabot Space and Science Center.
