Demonstration Tuning Fork - Large

Not every tunning fork is created equal! As you know you can hear the frequency of tunning forks, but on this one you can see the frequency (or a blurry version of it!). The large tines on the fork make the vibration visible so that while the fork emits waves (sound) at lower frequency. Set of two forks includes a larger fork with 50cm tines at 12Hz, and a smaller fork with 37cm tines at 38Hz approx. Also includes a detailed demonstration guide.
